Light & Heavy
Light & Heavy is a Pixar computer animated short, which was created by Pixar Animation Studios for Sesame Street in April 1991. It starred Luxo Jr., from the previous film with the character.
Luxo Jr. likes playing ball, so after entering the screen, he kicks the beach ball with his head passing it to his dad, Luxo Sr, who passes it back to Luxo Jr. He tries to push his new bowling ball, with his super strength, but it's not working, so he kicks the beach ball higher, and pushes the bowling ball, with much effort, while it pushes Luxo Sr. away from the screen.
