OMG, this green character from Among Us game has something on his head in our fanart Among Us Green Slug Sticker. The Headslug is a pet or hat in Among Us that looks like a green, blob-like creature with one eye and an antenna. This pet is a reference to Brain Slug parasites from the show Futurama. When a player wearing this hat is killed by An Impostor, the eyes of the hat each become an X, implying that the hat itself may be a living thing.
