Welcome to the Jungle Puns

Hey all! Sorry if this is against the rules somehow, but I am looking for some pun assistance. I'm a teacher and am setting my room up with a jungle theme. I want to decorate the door to my classroom to say "Welcome to the Third Grade Jungle..."We've got ...." with some kind of academic spin on "fun and games." Either fun or games can stay in the pun, but I figured I couldn't just straight up quote G&R without making it school related too. I'm usually pretty good at puns (post title nonwithstanding) but am coming up empty. Thanks so much!
