Ghoulies

Ghoulies appeared in the 1984 movie of the same name. They are horrible and mischievous little demons that act as the titular antagonists of the Ghoulies series of comedy-horror films, though they were not the only antagonists in the series as these impish creatures could normally only enter the world via the use of dark magic and forbidden ceremonies as well as highly stylized Satanic rituals. While mischievous and tricky, they are demons by nature and should be treated as dangerous beings.
