Gerald Jenkins was a childhood acquaintance of Johnny Ghost and Johnny Toast who they knew from Elementary School. According to them he ate crayons. He apparently liked to annoy Ghost and at one point Ghost threatened to kill him. Sometime later he died as an adult from unknown causes (Jimmy Casket?). His ghost later started haunting Johnny Ghost's apartment in East Belgium after Johnny Toast summoned him. Also haunting the building was Maxwell Acachalla who somehow ended up dead in one of the apartments. After jump scaring both Johnnys several times they eventually escape from him and Maxwell in a green car.
