Muttations

Muttations are scary animal-like creatures that are created by The Capital in The Hunger Games. Wolf Muttations were created in the first book to kill off the final competitors - Katniss, Thresh, Cato, and Peeta. Tracker - jackers are mechanically created bees to be deadly enough to kill with one sting. Glimmer and District 4 Female were both stung by them. There was also orange monkey muttations in Catching Fire that almost killed Peeta. Not all muttations, however, are used for killing.
