Asparagus, Gus for short, is a Zombie Horse owned by Stacy in Dogcraft.
Asparagus randomly spawned in Stacy's Quonset, where Joey, the donkey, and Cinnamon Toast, the horse, were already living. Stacy had no idea how it got there, but wanted to name tag it to prevent it from despawning. She named it Asparagus due to the green coloring of the animal.
After uninstalling the Mo' Creatures Mod, Asparagus was erased from the world of Dogcraft. Stacy announced this to the fans, and added Asparagus to the Cemetery.
Asparagus was magically revived many episodes later. While healing a Zombie Villager named Gus, Asparagus rose from the dead. During this off-screen process, the villager was renamed to Butch, as Asparagus thought that Dogcraft was only big enough for one Gus.
