A marmot (or groundhog, as per the English translation) is blasted by the heroes when they mistake it for something more dangerous. A (talking) barracuda fish is caught and grilled. The heroes also destroy monsters resembling giant animals, including a bug and a turtle.
The remains of a marmot blasted by one of the heroes, which doesn't look very realistic. A barracuda fish is caught and grilled by the heroes, but blatantly a puppet.
There is a LOT of gore. People are stabbed in the head, somebody is slowly pulverised, monsters are messily exploded, etc. It's all very cartoony in nature and played for absurdity, but probably not recommended for the squeamish.
Interspecies intimacy between an anthropomorphic rat and multiple human women. Mostly left to your imagination; we see him French kiss a woman in one scene.
