"A ball that can be thrown as an attack."
Pixar Ball is a Tool introduced in Disney Infinity 1.0. It can be unlocked in the Disney Infinity 1.0 Toy Story In Space Play Set Game, and in any later Edition by purchasing it in the Toy Store or placing the Game Piece on the Disney Infinity Base.
To use it, look (hold left trigger to aim) at the target, then pull the right trigger. The Pixar Ball will travel to the target, with no knock back effect.
