He is voiced by the veteran comedian and actor, Tim Conway .
Mulch is a fairly level-headed viking, often acting as the straight man to Bucket's stupidity. He also seems to be good-hearted. However he can also be selfish as he sometimes takes advantage of Bucket's dimwitted but goodhearted nature.
Mulch first appeared in How to Start a Dragon Academy alongside Bucket, having just completed a fishing run. Unfortunately, their catch was soon eaten by Dragons. Later on Snotlout and Hookfang scared a bunch of fish into their fishing nets, earning their thanks.
In Viking for Hire, Mulch had bought a sheep from Bucket, but refused to pay for it. Gobber, who was taking on some of Stoick's responsibilities, gave them a pair of weapons and had them fight it out.
He also appears in Animal House, trying to teach Bucket which animal gives what. After showing Bucket that the yaks are supposed to be giving milk he notices that the dragons have scared the animals into not producing anything.
He wears a helmet with four horns on it. He has a fat blonde beard which spreads around his face. Mulch has a green shirt with scale mail armor on it. He also has striped (tan and red) pants.
- Mulch resmbles R2-D2 from Star Wars and Pintel form Pirates of the Carribean because he is short but smart and has a tall but unintelligent companion.
- He along with Bucket and Gobber seem to be the most loyal vikings to Soick the Vast because in "When lightning strikes" Bucket, Gobber, and Mulch were the only vikings to protect Toothless.
