Nutcracker has had a wooden head since birth, and because of this has a very powerful and painful bite that likely can crack. He addresses all females as "Fräulein".
He was seen in Operation: N.A.U.G.H.T.Y., biting Numbuh 2's head to get back the "reindeer" Numbuh 3 allegedly had wrapped up as a present of Numbuh 4. It was later revealed that Numbuh 3 was only concealing a reindeer themed rainbow monkey.
- His voice is an impression of Paul Frees.
