Pipsqueak

Pipsqueak, or Pip for short, is a small bar-ba-loot with a white spot on his chest who appears in the 2012 Lorax film. He loves marshmallows and rode on the river with the Once-ler in the "Pipsqueak Rescue" scene.

His name is for sure revealed when the Lorax and the other animals in the Truffula Forest try to save him. He also loves Truffula Fruits and chose to grab a fruit instead of the Lorax.

A barbaloot resembling Pip appeared on Page 10 of the original Lorax book, marking a cameo. He loves the Once-ler, as a friend as they bonded during Once-ler's estance through the valley. Pipsqueak really seemed to like the company of the Once-ler.
