Rumblegum (Cursed Familiar)

Description: The rumblegum is a dangerous creature from the fey related to the lycanthrope family. It has two forms: a tiny and cute furry creature that looks like a cross between a rabbit and a raccoon and a large monstrous form with gangly legs and sharp claws. It is sometimes summoned as a familiar through a corrupted Find Familiar spell or by a spellcaster who has a particularly weak Wisdom score and fails to cast the ritual spell correctly. Once summoned, a rumblegum cannot be unsummoned or dispelled. It must be defeated. It is not initially aggressive and will be helpful and friendly in its tiny cute form. However, if it is angered it becomes monstrous and attack whoever upset it and that includes its master. Rumblegums are extremely possessive and jealous and do not like sharing their master with anyone else and will be antagonistic and deadly towards friends and especially loved ones.
