Nice work. The cartoony sounds fit well with the animation, even though they're almost a bit too exagerated, and the transitions between scenes are pretty interesting, like that SMB world style travel, the police bats running after the character, etc. You got that classic lightbulb too, and the teacher, heh, classic drama! :D Everything moves at a fast and fun pace, and the ending, haha. Nice work!
