Creepworms are a species of monster found in the Glowing Caves of Swaatch.
Alistair Neezley once claimed that, during an adventure in the Glowing Caves of Swaatch, he found himself surrounded on all sides by monsters called Creepworms. However, considering Neezley's track record, the veracity of this claim is likely tenuous at best.
Creepworms are mentioned in the 2019 Crew of the Copper-Colored Cupids story Misadventures in the Interdimensional Black Market. They share their names with a species of Heartless featured as minor enemies in the Kingdom Hearts franchise, although it is unclear if this is a coincidence or if the Creepworms encountered by Neezley were in fact of this type.
