Prince Varmint.A Viking named Sam the Terrible is rowing upriver towards a castle, and he is noticed by two people on a nearby riverbank, who retreat to the castle sensing an invasion. As he passes by Bugs Bunny's hole, Bugs peeks out and thinks that Sam's outfit is that of an "electric can opener broken loose". As Bugs sees Sam enter the castle, Bugs takes it upon himself to fight Sam. In Bugs' first confronting Sam, who is trying to get the locals to come out, Bugs calls Sam's outfit a Halloween costume, and takes the sword from Sam and dulls it, rendering it useless, and kicks Sam out of the castle. Sam tries to re-enter, only to see the horns of his cap get stuck in the castle door. In the meantime, Bugs paints a door on the castle walls to trick Sam, and Sam (this time with the help of a pink elephant) tries to break the "door" down, only to instead knock in some of the stones where the door was painted. Sam berates the elephant who then angrily slams Sam on the floor multiple times...
