Once Marius saw Max trying to climb a wall to enter the museum, he suspected him and Ash of being thieves and sent Spheal to battle. Spheal was too cheery and even attacked Marius using Water Gun, even if Marius meant on his enemies. Marius had Spheal use Body Slam, which bounced off the wall and hit Marius instead, making Ash and Max suspect Marius was a new trainer. Spheal managed to use Blizzard successfully, but was quickly defeated by Ash's Pikachu's Thunderbolt. Once Marius, Ash and Max were captured by Team Rocket, Marius had Spheal use Body Slam, albeit unsuccessfully. Fortunately, when Max and Marius jumped off a cliff to evade Team Magma's attacks, Spheal carried them across the sea to the beach.
