The Sloth Monster Lethargo is one of the Thirteen Monsters that appears in TMNT (2007 film). It is likely based on the Mapinguari, a sloth-like cryptid that has been reported as living in the Amazon rainforests.

Trivia

The name Lethargo comes from the book adaptations of the movie, but is the only official name outside of Playmates' generic "Sloth Monster" for the action figure.
