Oggy and the Cockroaches (1999)

S02E63 Chatter Box

Oggy gets his hands on a new kind of crackers that make anyone who eats them babble endlessly in gibberish. When Dee Dee takes a bite, he suddenly starts talking. However, the other cockroaches aren’t too thrilled about Dee Dee's newfound chatter, and neither is anyone else. Things take a turn when Jack decides to try a cracker himself, joining the nonsensical conversation.
