Fat Nuggets is a pink pig with various darker pink and black spots on his body, which they have been shown to be able to glow. He has large black eyes that have been shown to glow as well. He has both pink and black spikes along his body and he boasts a mouthful of pointy sharp teeth and a curly tail with a quadrilateral barb at the end of it.
- So far, Fat Nuggets is the only pet to appear on the show. In earlier versions and art, he was known as Wiggles.
- Vivziepop has stated that she is trying to figure out how to bring Fat Nuggets organically into the show, but does not know when or where exactly at the moment.
- An early reel design of him taken from the prequel comics can be seen on a poster in Angel’s room in the end credits scene of "Addict".
- In one of Angel's Voxtagram posts, it is shown that Fat Nuggets was originally given to him as a gift.
