We see fantastical creatures being decapitated, dismembered, shot and stabbed. All this involves gory details and blood spurts. To reiterate, the nature of this is comical.
NOTE: Although the violence is severe, it is still comical and is intended to be humorous in nature. The animation anyway is not very realistic and the graphic violent details tend to be more sketchy and comedic.
Terrorists attack Imaginationland. This is actually quite graphic; people are blown apart, a lot of blood and gore is shown, and several people catch alight.
A care bear is shot graphically in the head and is then decapitated.
Strawberry Shortcake is tied up and beaten, then her eye is cut out.
The Good and Evil characters battle against each other at the end with some bloody violence.
Popeye is raped by the Christmas critters on screen but it is played for laughs.
ManBearPig escapes the portal and kills many people at the pentagon in very gory ways. The people are graphically dismembered where innards show. This scene is replayed once or twice.
