Question: what are the mutts in mockingjay part 2?
Answer: Wolf "muttations" or "mutts" are engineered wolf-like creatures that appear at the end of the 74th Hunger Games to draw Katniss, Peeta, and Cato into a final fight. These creatures are hybrids created by mixing wolf DNA with the DNA of specific deceased tributes in order to cause them to resemble those tributes.
