The Predator

A number of Dinosaurs episodes featured a large swamp monster, which is green and has visible fangs. The swamp monster is a hand puppet, but matted to look like a giant creature. Every swamp monster seen on Dinosaurs looks identicle. Given the fact that many of the puppets on Dinosaurs were regularly reused as different characters, and the fact that there were never more than one swamp monster seen at the same time, it is unclear as to whether all swamp monsters look the same, or if all appearances by a swamp monster are actually appearances by the same swamp monster.

A swamp monster was used as the title character for the series Totally Hidden Predator.

It takes a few days before whatever a swamp monster eats to digest. .

The swamp monster puppet originally appeared in Monster Maker.
