Mojo

Mojo is a little doggie from the Movie continuity family.

"Here, lizard, lizard, lizard..."

Mojo is a male, smooth-coat Chihuahua owned by Sam Witwicky. He is coddled by Sam's mom (much to Sam's chagrin) and apparently has a very weak bladder.

Fiction

Transformers (2007)

Actor: Chester the Chihuahua

Although Mojo is Sam's dog, Judy appears to consider him her pet as well. She put a "Mojo's Penthouse" sign on his dog house and puts girl dog jewelry on him, claiming that it's his "bling". Sam argued that it was hurting his self-esteem issues, which he claimed were already heightened due to the fact that he was a Chihuahua.

Mojo broke his left foreleg shortly before Sam got his new car. Sam was carrying Mojo's pain pills when he was taken down to police headquarters, which made the overzealous officer there think Sam was a junkie.

The Orkin Man looked smaller on TV.

When the Autobots went to the Witwicky residence, Mojo made the mistake of releasing what the robots thought was lubricant on Ironhide's foot. Upon discovering this, Ironhide requested permission to terminate the "rodent," but Sam Witwicky frantically told Ironhide that humans love Chihuahuas. Ironhide agreed to spare it, complaining that the "lubricant" would cause rust.

Mojo was taken into custody with the rest of the family by Sector Seven, with Judy threatening to kick the ass of anyone who hurt him, but Mojo was later released with the Witwickys. The agent who had to escort Mojo to the van with a catch pole used to control vicious or stray dogs must have felt really silly. Transformers

Revenge of the Fallen movie

Actor: Chester the Chihuahua

Good news on three fronts: Mojo's leg is better, he has a lot more bling, and he has a new doggie pal named Frankie. Frankie is easily dominated.

As Sam was preparing to leave for college, Mojo relieved the stress of his owner's departure by dominating Frankie on the couch until an annoyed Ron Witwicky shooed them off and told Mojo not to dominate Frankie. Not to be deterred, Mojo and Frankie went out to the penthouse for some domination...at which point the entire kitchen came to life and started attacking Sam and Ron. Once they made it outside, the appliancebots located the penthouse and fired on it. Mojo ceased dominating Frankie long enough for the two to flee. After the danger had passed, Judy frantically carried the two dogs out when Sam's car set the house on fire. Revenge of the Fallen

Notes

• At one of the BotCon 2007 movie writers panels, it was revealed that Mojo was originally going to be a Bulldog (as one of the writers owned a Bulldog named Mojo growing up), but director Michael Bay decided to change the dog to a Chihuahua.

• Mojo's broken leg was caused by Judy accidentally loading him into the washing-machine along with a pile of clothes. This is only mentioned in the novelization, however, as dialog about it was cut from the final version of the film.
