Popplio is very playful and it likes to make bubbles for fun or claps its hands. At first, it is afraid of people, but under Lana's care, it becomes friendlier and likes to stick with humans.
Lana was using a Poké Ride Lapras and found saw several members of Team Skull intimidating Popplio. Lana had Lapras freeze the grunts with Ice Beam, then came to rescue Popplio. After taking it to the Pokémon Center, Lana fed Popplio and the two have been inseparable ever since.
Lana was fishing with Popplio. Once they saw Ash being startled by a Bruxish, they both started laughing, with Ash laughing as well. Later, Lillie watched over Popplio while Lana rode a Tauros along with the other Trial Captains. Once Ash came to the Pokémon School one day, Popplio made a watery balloon to surprise him, as Lana and others made a surprise party for Ash. Lana also had Popplio race Pikachu. Though Pikachu was quicker than Poppio on land and swam as fast as he could, Popplio was much faster at swimming and won the race. Lana praised Popplio and told it that it was amazing. Lillie later explained to Ash that Popplio could swim up to 40 kilometers per hour. Popplio was with its trainer, who went with Ash to see what new Pokémon he would catch in the forest. Popplio also watched as Team Rocket appeared, who threatened to steal all their Pokémon, and how they were dragged by a Bewear. After Ash's Pikachu got hurt in a battle against Grubbin, Popplio went with its trainer away to report to Professor Kukui what happened.
As Ash went to school, he saw Lana training her Popplio. Popplio tried to make a watery balloon, but failed and fell in the sea. Once she arrived to school, Lana and Popplio heard that Lillie had a secret weapon for fishing. Popplio clapped and jumped into Lillie's lap. Lillie was terrified, so Lana took Popplio back and both apologized to Lillie. Once school was over, Popplio had a race with Pikachu on the beach and won. After Lana told Ash how she met Popplio, she had it emit water balloons, which splashed and soaked Ash. Regardless, she admitted she wanted to have Popplio make a big balloon so they could travel under sea and meet lots of water Pokémon. Ash was confident Popplio was capable of achieving that dream; Popplio tried to make one, but failed and soaked Ash and Lana. During fishing, Team Rocket stole the group's Wailmer and Lapras. Just as Pikachu freed the Pokémon from the net by using Iron Tail, the Pokémon were to fall on rocks. Fortunately, Popplio managed to emit a giant balloon, which saved the Pokémon, who dived into the sea. After Team Rocket's defeat, the group praised Popplio, who emitted one more balloon and enveloped Ash and Pikachu in it. However, the balloon soon splashed and made Ash and Pikachu fall down.
The class spoke about the Rattata and Raticate problem and found out the solution were Yungoos and Gumshoos. Their yelling startled Sophocles' Togedemaru, who ran in circles and knocked Popplio and Mallow's Bounsweet off the table. Pikachu managed to stop and calm her down, but Togedemaru started showing affection towards him. Popplio, along with its trainer, was at the party to celebrate Ash and his Pokémon's Grand Trial of Melemele Island victory. Lana and Popplio spent a day on the beach with Lana's classmates. After the class's task was over, Popplio emitted bubbles to play volleyball with.
Lana and Popplio participated in the Pokémon Pancake race. However, in the third part of the race, Mallow's Bounsweet accidentally bumped into Mimikyu. This caused Mimikyu to fire Shadow Ball on Lana's Popplio's bubble and pierced it (the attack was meant for Ash's Pikachu). This caused Bounsweet, Mimikyu and Popplio to be disqualified. The next day, Popplio watched as Lillie's egg hatched into a white Vulpix and Samson Oak's egg into a red Vulpix. While the white one, Snowy, ignored the group, the red one wanted to play with the others. The next day, after Lillie befriended Snowy and hugged it, Snowy was more interested in playing with the class's Pokémon. Lana and Popplio were at class when Ash explained how Rockruff came to the house wounded the other night. Popplio emitted a bubble, which splashed Bounsweet, Pikachu and Togedemaru. They also watched Ash train Rockruff.
Lana had her Popplio demonstrate creating a balloon and let Pikachu enter inside. Suddenly, Mallow's Bounsweet sneezed, causing Ash's Rowlet to be attracted to her. Bounsweet repelled the attack, causing Rowlet to be bounced away. Accidentally, Rowlet hit Popplio and the two entered the balloon, which flew off on the wind. Popplio tried to calm down Rowlet, who believed Ash deeply cared about it, and thought Lana would scold Popplio. Suddenly, Rowlet, again by accident, pierced the balloon, causing Popplio to fall down. Rowlet tried to grab it and fly away, but Popplio was too heavy for it. Thus, Rowlet and Popplio fell on Team Rocket, who were making a device. As Popplio and Rowlet started apologizing, the latter realized it had a strange ring around it and couldn't fly. James had Mareanie fire Spike Cannon, but was repelled by Popplio's Bubble Beam. As Rowlet and Popplio fled, Meowth and Mareanie chased after them, while Jessie and James were grabbed by Bewear. Popplio had to bounce Rowlet on top of its nose, but tripped over a rock, injuring itself and Rowlet. Meowth and Mareanie appeared, as the latter tried to attack the two. However, the two were rescued by Litten, who knocked Meowth and Mareanie out. Since they had nobody else to turn to, Rowlet and Popplio joined Litten, who took them to a place under the bridge. There, the old Stoutland licked Rowlet, sensing it was Ash's. Popplio confirmed this by clapping, but it was worried where they were even, and even hit Rowlet for getting them lost. Stoutland had Litten get Rowlet and Popplio to Ash's house, though Litten hesitated a bit. After walking through the city, the trio stopped to a building, where they were captured in a net by Team Rocket. Litten burned them with Ember though it wanted to join Team Rocket to let Popplio and Rowlet free. Team Rocket was touched by this and just as they went to unlock the cage, Litten betrayed them by freeing Popplio and Rowlet. Popplio fired Bubble Beam, wrapping Team Rocket inside the bubbles. The trio combined attacks, making Team Rocket blast off. Ash, Mallow and Lana arrived, pleased their Rowlet and Popplio were fine and safe, but also noted Litten's presence.
Lana had her Popplio practice making the balloon. Popplio created one, which Lillie's Snowy entered. Snowy was amused, as Popplio started to bounce the balloon up and down. Seeing Ash was taken inside Palossand, Lana had Popplio use Bubble Beam. However, Palossand recovered from the attack, due to its ability to become stronger from such attacks. Instead, Popplio went to search for the shovel and had Pikachu wrapped inside its bubble to help in the search. After some time, they found the shovel, but as Popplio emitted the bubble to take the shovel, a lot of Water-type Pokémon were in the way and got wrapped instead. After some tries, Popplio and Pikachu returned with the shovel and bounced off the bubble. With Litten's Ember, the shovel stuck into Palossand, and it stopped outraging. During the Pokébase match, Popplio and Lana were on Ash's team. Popplio conjured a bubble to grab the ball. It also used its fin to hit the ball Kiawe threw. However, Popplio's fin got hurt. In the next match, Lana hit the ball Kiawe threw hard, enabling herself and Popplio a home-run and a definitive victory.
While going out camping, Popplio relaxed in the river. Due to Morelull's presence, Popplio fell asleep and was drained, along with others, except Lillie. Instead, everyone had dinner to end their hunger. Not soon after, the group encountered the Morelull, who, once again, made them asleep and drain them. Ash gave some of the energy to feed Morelull, and consecutively ate the curry Mallow made. Morelull was fed up and went to the tree, where everyone, including Popplio, watched as the Morelull evolved into Shiinotic. The Shiinotic Ash fed turned them asleep. The next day, however, everyone woke up and found themselves not hungry at all, seeing that Shiinotic returned the energy it drained from them. Before the class started, Popplio had a race with other Pokémon around the room, a race Pikachu won. During the exchange, Kiawe traded his Turtonator with Lana's Popplio. While working on the farm, Kiawe wondered what he'd do with Popplio, so Mimo decided to spend some time with it. The next day, Mimo reported the Tauros were fighting with each other. Since Turtonator was absent, Kiawe had Popplio emit the balloon to douse the Tauros, preventing their fighting. Kiawe was amazed, and had Popplio use Bubble Beam to wash the Tauros. Returning to school, Kiawe gave Popplio back to Lana and was impressed, seeing how Lana and her sisters cleaned Turtonator's back.
Olivia, who came to the Pokémon School, wanted to meet the heroes' Pokémon, and met Lana's Popplio. Popplio accompanied Lana, who was riding Stoutland to search for the treasures and bring them to Olivia. Since Stoutland disobeyed Lana, she and Popplio left it to sleep and search for the treasures on their own. Suddenly, Popplio was attacked by a Garbodor. Popplio used Bubble Beam to retaliate, and Lana took it and retreated. Lana tripped over a rock, and Garbodor caught up to them. Popplio used Bubble Beam to stop Garbodor, but was injured by its Sludge Bomb attack. Lana nevertheless thanked Popplio, and swore to protect it and Stoutland. The latter defended Lana and defeated Garbodor.
Popplio joined Lana and Ash to fish out a mysterious Pokémon lurking in Brooklet Hill. During the fishing trip, Lana encountered an injured Wishiwashi flopping around. Once it was healed, Lana went back to fishing. When all of a sudden, Lana's fishing line got hooked by a Totem Wishiwashi in School Form. Popplio was terrified by it due to its ginormous size. However, after seeing how much Lana is struggling to reel it in, it eventually conquered its fear and goes to battle it. During the battle, it got blasted away by an Alomomola. But Ash and Pikachu drove Alomomola away and Popplio proceeded to finish the battle with its newly learned move, Aqua Jet. Which also helped Lana clear the trial and earn a Waterium Z.
