Long Underwear Wolves are wolves that reside in Transylberia. There appearances are known for wearing red pajamas. They only communicate in growls and are translated by an off-screen translator with subtitles included.
A rather plain looking underwear wolf appeared in "Squirreled Domination" planning to eat Vambre. Since Vambre was running away from the squirrels and didn't notice the wolf, the wolf called her out on being rude. Then the wolf was pummeled by the squirreles with a tombstone saying "Here Lies Random Wolf". His head pops out and he says "Again, rude!".
Actual underwear wolves appear in the episode "Flirty Phantom" trying to eat the Warriors for Hire. But the huge Snowstorm caused all of them to fly away.
- The random wolf's voice is similar to Kermit the Frog, even the scream.
- The name is of course a play off of "werewolf".
