Disguise Da Limit
Timmy (aka "Phantom") arrives late to register for the Pokémon Contest, because his mother gave him lots of homework to do. His father let him go, and confronts the mother when she comes to check on Timmy.
Jessie is competing under an alias in the Contest, and her Dustox takes the lead in the first round. May's Skitty fails to do a Blizzard attack, losing points and putting May behind. May still progresses to the second round.
In the second round May quickly dispatches her opponent, while Phantom beats Jessie in a tough battle. Jessie's disguise is blown off, and after losing she decides to try to steal Phantom's Dusclops instead. Pikachu sends them flying with Thunderbolt, also ripping off Timmy's mask.
Meanwhile, Timmy's father talks to his wife and brings up the fact that she only hates Pokémon because her parents took her beloved Poochyena away from her when she was a child. She relents and decides to cheer Timmy on at the Contest.
May and Timmy face off in the final round, and Skitty isn't doing so well until May instructs it to use Assist. Skitty quickly catches up and beats Dusclops. Timmy's mother encourages him to continue competing.
