a giant baby

A baby with a tuft of yellow hair and a diaper runs across a suburban lawn, smiling widely and waving his hand. The scene cuts to a boy with white hair and a bandage on his head, wearing an orange shirt and blue pants, standing in a bedroom with a green puddle on the floor, looking distressed as he stares at a messy desk with a spilled green substance and a blackboard with equations. The baby is then shown peeking over a ledge with a wide, excited grin.
