Mojo the chihuahua, again played by Chester, returns in Transformers: Revenge of the Fallen (2009). This time he has a French bulldog as a dominated friend. Initially, in the first film, Mojo was supposed to be played by a bulldog, and it was a last-minute decision of director Michael Bay to cast a chihuahua instead. So it's only fitting that in the sequel Mojo should have a bulldog pal

The photograph below shows Chester in one of his other gigs. He's on the beach in mouth of fake alligator, filming a Vault Energy Drink commercial for the Coka Cola company. In the commercial a man drinks Vault to gain the energy to leap in the water and save the dog from the reptile.
