Crazy Baby is a fictional character from Uncle Grandpa and the main antagonist of Driver's Test. He is voiced by Eric Bauza.


He is a baby with peach-colored skin, thick eyebrows, sharp teeth, and a demented look in his eyes. He also wears a diaper.


Crazy Baby is, as his name implies, crazy; doing random acts of destruction for no apparent reason. Since he's still a baby, he is easily distracted by toys, such as a stuffed rabbit.


Uncle Grandpa

Uncle Grandpa is the main cause to Crazy Baby's existence. In Driver's Test, Mary couldn't shift into reverse while parallel parking, so Uncle Grandpa shifted into the gear that said "Crazy Baby" and that's when Crazy Baby was spawned from a cloud and into the universe. Crazy Baby is one to get angered very quickly and especially to Uncle Grandpa when he arrived back into the RV and said good morning to Crazy Baby.


Just like Uncle Grandpa, Crazy Baby is quick tempered to anyone, Crazy Baby took over the RV and began driving it into a volcano in the city, after Uncle Grandpa calmed down Crazy Baby, Mary took over the driving and drove away from the volcano. Mary also returned Crazy Baby to Remo's Dad.

Remo's Dad

Mary had returned Crazy baby to him, and Remo's Dad claimed to be the father. The two showed similar qualities such as vicious looks.


Although the two never interacted, it is implied that Crazy Baby is Remo's brother as they both share the same father.

Priscilla Jones

In Uncle Grandpa Retires, Crazy Baby kept on throwing bottles of milk at Priscilla and at one point she finally had enough and she made Crazy Baby crash his car into a tree leaving him crying and milk pouring from his car.

Tiny Miracle

In Uncle Grandpa Movie, these two got off on the wrong foot as they both were sitting together in the movie theater, and Tiny Miracle asked Crazy Baby if he's ready to see the movie, and Crazy Baby squirted milk on Tiny making him surge out.

  • Crazy Baby's car in Uncle Grandpa Retires is different from the one in Driver's Test.
  • If the shifting gear had said "Crazy, Baby!" this would make more sense to be a type of speed rather than spawning an actual crazy baby.
  • Crazy Baby can communicate with other babies as seen in Driver's Test.
