SPONGEBOB BETRAYED US!!

Patchy's response towards the lost episode appearing to just be SpongeBob going through some walk cycles is to furiously accuse SpongeBob of betraying him before tearing down all of his SpongeBob merchandise and declaring that he will run away. As soon as the real lost episode starts playing and his parrot Potty informs him that there's more, the scene of Patchy's tantrum is humorously played in reverse.
