Peaches is a huge warthog and Grim Gloom's slow pack animal.
Peaches is a large brown hog with yellow eyes and two long teeth pointing upwards.
Peaches appears to be quite loyal to the Glooms, always transporting them and any important cargo. That said, while she is strong, she is also rather slow which can make things problematic for her masters.
In the series
Peaches serves as their beast of burden in the series with the following:
In "Sneezin' Season", she took the Glooms and their spell-making pot to Jollywood.
In "Surprise", Grim used her to make his getaway from the 7D after stealing the party decorations. Her slow pace allowed the 7D to catch them though.
In "The Jollywood Jam", the Glooms are probably aware of Peaches' extremely slow speed, so they added roller skates on her to get them to the Jollywood Bowl faster. But she and the Glooms lost control of the wagon and they separate, leaving behind the wagon with Glooms and crashed into the 7D at a crossroads.
In "Frankengloom", the Glooms wanted to trade her in to a salesman while on the way to Queen Delightful's castle; instead they keep Peaches and are given a pig named Cream. The two began to fall in love, while still traveling slowly. Cream is only seen in this episode so far.
