| character | purpose |
| the monster | Stalk the swamps, grunting a lot. It's supposed to be a giant mutated "nutria"...what in the HELL is a "nutria" anyway?!? update from 7/15/05: I finally remembered to find out just what a nutria is. |
| the fat poacher | Be the token opening-scene monster victim. |
| Frank the game warden guy | Look like Alex Trebek, run around doing things in order to give this movie a protagonist. |
| Frank's boss | Tell Frank it's okay to do things he was going to do anyway. |
| police chief | Set up meetings in coffee shops so that the filmmakers don't have to pay for a police-station set. As a bonus, he also looks like Andy Griffith. |
| police chief's son-in-law | Be gung-ho and ask stupid questions. |
| police chief's secretary | Answer the phone and relay messages to the chief. |
| doctor | Examine bodies and come up with theories so the other characters have something to talk about. Also looks like Alex Trebek. |
| generic policemen (3) | Give the police chief someone to boss around. |
| Papa Joe | Old drunk bastard who makes moonshine and yells at his sons. |
| Jesse | Son #1 of Papa Joe, big beefy violent guy who stole some dynamite but isn't sure what to do with it. |
| T-Bob | Son #2 of Papa Joe, really fat guy, someone for Jesse to boss around. |
| Bubba | Token black character, poaches with Jesse and T-Bob, looks and acts like Buckwheat. |
| old scientist | Develop a mutated strain of "nutria" so that furs will be bigger and worth more money. |
| young scientist | Token geek, turns out that he was the one who accidentally injected the normal "nutria" with human hormones, thus creating a giant "nutria." Yeah, sure, buddy. Whatever. |
| the corporate backers (2) | Fly down to the swamp, give the old scientist a 30-day deadline for results, then fly away. |
| Sally | Token old Indian for the old scientist to call "old hag" 16 times. Ends up tricking both scientists into walking through quicksand and drowning. |
| random boat driver | left alone so he can be shot accidentally by Green Berets. |
| Green Beret leader | Skinny little nerd who we're supposed to believe is a Green Beret. Utterly non-intimidating. |
| other Green Berets (2) | Allows the Green Beret leader to have someone to boss around. One carries a rocket launcher. |
| Baggett | Young local kid with rifle. Mistaken for monster and almost shot by Green Berets (see 'random boat driver' above.) |
| drunken rednecks in boats (dozens) | Form their own posse to hunt the monster, they end up drinking a lot and driving their boats around in circles. |
| Helicopter pilot | Sent to make the drunken rednecks in boats go home, but quickly becomes target for the drunken rednecks in boats, all of whom are armed. |
| Biplane pilot | Succeeds where the helicopter pilot failed, spraying the drunken rednecks in boats with insecticide and making them all turn around and go home. His strafing runs are set to the rousing sounds of fiddle music. |
| random hunter #1 | Becomes victim #3 of the monster since nobody has died in half an hour. |
| random hunters #2 and 3 | Become victims #4 and 5, for no apparent reason. |
