While heading to Mossdeep City, Ash and co. notice a life preserver belonging to the Spoink they met before. The reunion is cut short as Spoink's pearl goes missing again. It lands up on an island and Ash and co. try to find Spoink's pearl. Will they find it... again, and how is it possible that a Spoink can balance a Wailmer on it's head?
The gang goes to Mossdeep City via a boat for Ash's next Gym battle. They spot a Spoink - the same one before - on a log floating. They immidiately go to catch it and bring it on the ship. Spoink bounces being happy, but trips and its pearl falls into sea. They are amazed when Spoink lost the pearl - twice. Spoink sees a ball and places it on its head, but Ash removes it. Torkoal cries and goes in water to get the pearl back, but sinks. Ash goes in to save him. May thinks it was cute that Torkoal wanted to save the pearl. Ash sends Coprhish and Brock Mudkip to help in the search. Max thinks Lombre should also be sent, so Brock does it, but Lombre just swims.
Corphish and Mudkip return with no pearl. They go to the shore of an island, sad when they have no idea where to search. A boy runs with an Azurril and Spoink places it on its head. The gang removes Azurril, but Spoink places more Pokemon - even a Wailmer. A man arrives, seeing Spoink lost its pearl, so gives them help. He thinks a Clamperl will help them. The man introduces himself as Isaiah. He shows them the Clamperls, saying Clamperls make the pearls which can Spoink use on top of its head. However, none of the Clamperls have a pearl yet. Spoink bounces, seeing a blue pearl. Isaiah has no idea how it is made, but bets that he will discover soon enough.
They go on the beach, trying to get the pearl from a Clamperl. Spoink uses Psychic to put a Shroomish on its head, but May takes it and gives it to a little girl whom Shroomish belonged to. Team Rocket arrive in the lab, while Meowth imagines the boss with the pearl. As about Jessie is to take the pearl, Spoink places it on its head and bounces away. The gang hears the alarm, so they go inside. Team Rocket, dressed as janitors, explain that Spoink gone off with the pearl. Ash sends Swellow and May Beautifly to search for Spoink and the pearl. The gang also splits to search. Meowth thinks both the pearl and Spoink should be given to the boss.
Spoink bounces and the children with the Shroomish and Azzuril come, hiding their Pokemon. Spoink trips over and the pearl is deflected from rock to rock, until it reaches a Clamperl. The blue replaces a pink one and the pink one deflects to Spoink. Beautifly returns and leades the gang to Spoink. They see that the blue has been replaced with a pink one. The children tell them what happened to the blue pearl. They go to the site, while Team Rocket overhear them. They arrive, but see Clamperl being encased in its shell. Clamperl's shell opens, so May negotiates with Clamperl. She succeeds, but a smoke bomb explodes - Team Rocket arrive.
Jessie sends Seviper and Ash his Torkoal. Seviper goes to bite, but fails when Torkoal used Iron Defense. Torkoal attacks with Flamethrower, but Seviper dodges. Seviper uses Haze, dimming the vision. Team Rocket goes away, with Clamperl inside the bag. Afterwards, Clamperl's shell opens, revaling to Team Rocket the shiny pearl. Clamperl's shell closes, so James goes to open, but fails. Meowth tells them Clamperl needs to be talked to. They begin to brag about Clamperl, but nothing happenes. Meowth thinks that boss will be annoyed by Clamperl as a present, so realizes they should tickle Clamperl. Clamperl's shell opens, so Meowth tickles it more, but his tail is being closed, along with the shell.
Afterwards, Clamperl's shell opens, but closes soon after. James thinks of an idea - he sends Chimecho and tells it to sing for Clamperl. However, Clamperl's shell does not open, angering Jessie. Jessie begins to talk to Clamperl, but uses Water Gun, pushing her. Swellow spots Team Rocket and leads the gang to them. Team Rocket try to use sticks to open the shell, but the gang encounters them. Spoink uses Psychic, pushing Team Rocket. Jessie sends Dustox and James Cacnea and Ash Grovyle. Dustox goes to tackle, but the attack is negated by Grovyle's Quick Attack. Cacnea uses Pin Missile on Clamperl, though the attack is stopped by Spoink's Psychic. Grovyle attacks with Bullet Seed, hurting Dustox. Spoink uses Psi-Beam, hurting Cacnea.
Dustox uses Poison Sting, but misses, so Grovyle counterattacks with Leaf Blade, damaging Dustox. Cacnea uses Needle Arm, but is pushed by Spoink's Psi-Beam. Clamperl uses Hydro Pump, blasting Team Rocket off. Ash says to Clamperl that Isaiah needs the pearl. Spoink gives its pearl to Clamperl for the blue pearl. However, Spoink is sad when it does not have its pearl, but Clamperl decides to give its pearl to Spoink. Spoink places on its head the pearl and bounces happily.
