SC X False Hydra

Story: All the smiling Critters, are having a picnic, CatNap decides to go back to DogDay's house to get food while the others get everything else ready, Then here's a strange sound. About the false Hydra: The false Hydra is From D&D (dungeons & dragons) The False Hydra sings a song/lullaby that anyone in a 30 mile radius, makes anyone who hears it not able to see it even if it's right in front of you, (Only elves are immune to the false Hydra song/lullaby) And the only time it stops singing is when it is eating, that is why they usually lower their victims into forests or caves, And and when a False Hydra eats a person that person is wiped from history, for example a person who has a best friend and they have a picture of that picture will not be changed but their friend will forget who they are but the picture will not be changed. (Also this isn't canon I don't think, but the False Hydra can make people hallucinate, anyways I'm not explaining every little detail about the False Hydra)
