A Hypnogrif is a hypnotizing Slug. Eli Shane gained one after using Doc to unghoul it. A Ghouled Hypnogrif is called a Cryptogrif and can make people become minions. Mister Saturday had a Cryptogrif in the episode "Dawn of the Slug". A hynogrif has been seen in a cage in "Bandoleer of Brothers" ready to be ghouled. They can read minds, and when transformed it looks like a hawk without wings. They are yellow and blue, with pink bulls-eye shaped eyes. Their preferred habitat is Deadweed Cavern, wetlands, and marshes.
