The goat is a hollow-horned, bearded mammal, originally indigenous to mountainous areas. There is one particular goat, that first appeared in Walk Like An Egyptian - Part 1 as Team Chris Is Really Really Really Really Hot's prize, that keeps making reoccurring appearances throughout the series. It can be distinguished by the red ribbon bell around its neck.
In Riot On Set, Gwen mentions that she had a job at the petting zoo and she had to clean up after the goats. In the same episode, Duncan, while acting, mentions a goat that his character had in their youth.

In Walk Like An Egyptian - Part 2, Team Chris Is Really Really Really Really Hot is able to perfectly balance their team on the goat despite its small size. The goat is able to move the group across the desert and they are the first ones to make it to the Nile River. The goat seems to have a very good relationship with Alejandro, as it jumps into his arms while they paddle across the Nile. Since the team is able to keep the goat with them during the entire challenge, the team is safe from elimination.
In Slap Slap Revolution, Chris orders a vicious, rabid goat to charge the contestants. However, it encounters one of the local goats, which is much bigger and seemingly more ferocious.

All of the animals attack everyone in the studio, with the goat ultimately attacking the camera and Geoff.
