The mudhorn was covered in wooly fur often coated in mud.
Mudhorns had a large horn, flat teeth, and long, wooly fur. It was oviparous, laying a single egg per clutch. The egg was huge and was cherished by Jawas. The exterior of this egg was woolly in the same manner as the skin of the mudhorn, and the interior yolk was yellow.
In 231 BBY, a mudhorn was in captivity at the Lonisa City Zoo. During the Nihil's attack on the Republic Fair taking place in the city, the animals in the zoo broke free. The zoo's mudhorn soon charged Jedi Padawans Ram Jomaram and Lula Talisola, but Talisola used the Force to trip the animal. The mudhorn crashed sideways into the ground and slid into a storefront, causing it to shatter. The creature then stood and lumbered away.

Around 9 ABY, a mudhorn encountered and fought Din Djarin, a Mandalorian bounty hunter, as the latter attempted to retrieve an egg from the mudhorn's cave. It was ultimately killed with the help of the Force-sensitive child, Grogu. The mudhorn later became the signet of the new Mandalorian clan that was founded with Djarin and Grogu.
The mudhorn first appeared in Chapter 2 of Jon Favreau's 2019 Disney+ television series The Mandalorian, directed by Rick Famuyiwa, which aired on November 15, 2019.
