The Lost Lapras (Japanese: ラプラスをたすけろ！ Help Lapras!) is the 4th episode in the Pokémon: Adventures on the Orange Islands.
After the crash of the blimp, Ash and Misty managed to get into a town. They spot some thugs trying to intimidate Lapras. Ash and Misty scatter them away, while a man named Tracey appeared to draw Pikachu. Seeing Lapras injured, the heroes take the Lapras to Nurse Joy. Hearing from a group of children about the Orange Crew, Ash wants to compete in the Orange League, to which Oak grants him this wish. As the heroes attempt to get Lapras' trust, Team Rocket make their plans to steal it. However, it turns out to have a beneficial effect for Ash and Lapras...
The blimp crashes, causing Misty and Ash to wake up. However, they see the island seems deserted and wander a bit. After a while, Misty proposes to wait for a while, being exhausted. She believes this is a deserted island and will have to eat bugs and berries, much to her and Ash's distaste. Suddenly, a grup of tourists come, kicking Ash and Misty away to have pictures with Pikachu and Togepi. They arrive to the Pokémon Park, where two ladies give them flower necklaces, as they arrived into a town, pleasing Misty and Ash they don't have to eat bugs.
Misty and Ash notice a group of thugs, who are intimidating a Lapras. Ash and Misty arrive to tell them to get off, trying to protect Lapras. The thugs are not pleased they interfere, so send a Spearow, a Hitmonchan and a Beedrill. The Pokémon charge, but are stopped by a man, who examines the Pokémon closely. Though seeing the thugs' Pokémon are not taken care of very well, he notices Pikachu is trained very well, with its shiny coat. He goes to measure its electricity, but the thugs attack. Pikachu uses Thundershock, causing the men, the thugs and their Pokémon to be electrocuted, as they run off.
The man notices the Lapras is hurt, so gives Ash a spray to treat Lapras as he goes to ger Nurse Joy. Ash goes to give it, but Lapras rejects, pushing the spray away. At the Center, Nurse Joy confirms Lapras will heal in time, though the man sees Lapras is a baby, as during the recent storm it must have been separated from the others and due to the thugs' behavior, it does not want to be with humans. Ash sees the man knows a lot about Pokémon. Nurse Joy tells it is because he is a Watcher, a person who studies the behavior of the Pokémon by traveling around the world. Ash and Misty introduce themselves, while the man is Tracey. They agree to take Lapras back to ocean.
Team Rocket observe and think about catching that Lapras. Suddenly, a group of children stomp on James to enter the Center, training to challenge the Orange Crew. Ash hears this, so Tracey explaines they are Gym Leaders around these islands, so if one were to beat them all, he/she can enter the League itself. Ash thinks of going to the League, but Misty pulls his ear, as they need to ask Oak for permission, as they still haven't delivered the GS Ball. Ash contacts Oak, telling him the GS Ball is safe and wants to compete in the League. While Oak thinks delivering the GS Ball is important, he lets him go to the Orange League. Tracey is happy he saw Prof. Oak, his famous hero, making Ash and Misty a bit surprised Oak was famous. Tracey announces he will travel with them to meet Oak in person. Misty is annoyed he "let himself join", but Nurse Joy comes with news Lapras is fine.
The heroes attempt to get Lapras to them, but it is too shy. Ash has an idea - he'll sing a lullaby to calm it down, since it helps children to calm down. As Ash goes to sing, Jigglypuff appears and sings, causing everyone to sleep. As the heroes wake up, they have drawings on their faces, including Tracey's drawing of Jigglypuff. Ash cannot wait and tells Lapras to get back into the ocean. Lapras goes away, so Ash dives in, hoping to get Lapras, but no luck. Suddenly, Team Rocket blast their bombs and introduce themselves. Tracey runs to them, as he heard Meowth talking and wants to record his voice. Meowth is flattered, but gets pounded, as Jessie and James are not impressed, as they want to steal Lapras. James sends Weezing, who uses Smog and Team Rocket escape. As they are moving too fast, Tracey sends Venonat, who tracks them down.
The heroes use the bikes to follow Team Rocket. Team Rocket move out faster, but Ash jumps and gets on the van. Ash goes in to make trouble, though Misty and Tracey are exhausted. Pikachu electrocutes Team Rocket, causing James to press a button, separating Lapras from the van. Ash goes out and Team Rocket try to stop the van, but get flipped out from the end of the road. Ash goes to untie Lapras, but the wagon goes down the road. Ash sees the wagon will fall to the ocean, so pulls the wagon, casuing it to go left, avoiding the cliff. Though he made it, there is another cliff, so he and Pikachu attempt to pull, but fall down. Ash and Pikachu calm down Lapras, knowing if they stick together, they will be fine and fall in water.
Misty and Tracey search for Ash. Tracey asks Venonat if it is sure they are around, to which Venonat confirms. Suddenly, Tracey and Misty see Ash and Pikachu arriving on a Lapras. He knew Lapras would trust him enough to catch it. Later, Ash promises to Nurse Joy to find Lapras' friends. They ride Lapras, hoping Ash will defeat one of the Orange Crew.
