A rabbit exclaims "What? Like this is the first time I've gnawed my own feet off?" and his severed feet are shown dangling from a hook.
Lots of mild violence (characters repeatedly get slapped, knocked over, thrown etc.) Most of it is played for laughs.
The entire film has a very dark tone but it is all done with pseudo-scary imagery. No blood is ever shown.
A rabbit who is immortal constantly tries to kill himself using various methods such as flattening himself and consuming poison. It is all played for laughs as he regenerates each time. However, in one scene, an explosion blows off the rabbit's face and you briefly see his brain before his head returns to normal.
A man and a woman repeatedly slap an Igor which causes him to pass out. In a separate scene, when they are about to slap him again, the Igor knocks himself out.
A man steps into a rocket ship which blows up, leaving behind nothing but his severed, mechanical hand.
A man dies when he is crushed by a falling piece of machinery (his corpse is not visible.)
A monster destroys several machines in hand-to-hand combat. Later, the monster starts pulling on the cables that hold up the arena in order to demolish it but is stopped.
Igor and two of his friends get caught on a conveyor belt that slowly takes them toward an incinerator as they try to escape.
