You're Too Little! (Tu es trop petit) - S1.E28

Harry is tired of being small. He's always trying to reach up for things, but ends up needing help. He wants to do things on his own. His Nana suggests drinking milk, but it doesn't seem to help him grow fast enough. He visits Dino World, where he finds a mechanical cow with milk that can instantly change his size. He tries it out, but finds that sizes it's changing him too are definitely not ideal.
