The Monocerous is a vicious, bull-like monster who attacks people all over Neopia. He can paralyse victims with its bellow. He is known for boasting about the numbers of Neopets he has eaten. Its favourite food is JubJubs which, ironically, are the only Neopet immune to the monster's bellow. The Monocerous also sometimes eats Wockys.
- In the early days of Neopets, the Monocerous was featured in the Gallery of Evil before the revamp in 2001. This article told us that the only creature immune to the beast's yelling is the shy little JubJub.
- Its name may be based on monoceros, a faint horse constellation in the winter's sky.
