-Tomeworm's are small slug like creatures of Grimm

Appearance: Possibly the smallest Grimm recorded, Tomeworm's only grow less than 30cm in length. Often hiding in damp and dark places. The plating over its mantle is relatively fragile, comparable with a snail shell. This plating has multiple holes in it where the Tomeworm's various red tendrils extrude. Its rear half is black with small patches of shell along the top. Tomeworms posses four eyes; two main larger eyes and two smaller secondary eyes. It moves similar to a gastropod, with a single black foot and mucus.

Abilities & Powers: Though it is the weakest of the known Grimms it is still possibly deadly. Tomeworm's secrete a necrotic toxin which may cause serious injury and may even require amputation if not treated immediately. The mucus it secretes is much safer and extremely sticky, enabling it to cling to any surface. Even with four eyes the Tomeworm may have poor eyesight. The two large tendrils have sensory receptors, enabling the Tomeworm to feel around it.

Name: Its name is a play on Bookworm

(Worms aren't listed as a species on Furaffinity huh)
