The TMNT monsters
 

So after rewatching the 2007 movie (just received my bluray version today) did we ever get the confirmation of the names of the cryptids(?) of the movie

the only ones I could recognize were:

Bigfoot
Jersey Devil
Muhuru (number 13 I believe)
and I can't remember the cryptids name, but the bat creature

Bigfoot is also known as Sasquatch in the Mirage Comics Monster Island issue. The bat creature was Vampire Succubor. The other monsters in additon to Jersey Red and Muhuru were Centaur, Sloth Monster (known as Lethargo in the book "The Legend of Yaotl), Spider Aracknor, Vampire Succubor, Sea Monster, Parrot Monster, and Crab Monster. (It almost sounds like leftover Sesame Street character names, doesn't it?) Two other monsters were unnamed and only briefly seen.
