Gahroo

A Gahroo is a demon monster in Daniel Kravitz, Chosen One, a segment of It's All Been Done Radio Hour.
The only member of the species that has been described so far is Grezit the Green. It has not been confirmed if all Gahroos look like Grezit or not. Grezit has a forked tail, green skin, multiple small chests, five claws and hands, six ears, sharp fangs, black ooze in place of blood ("Get Out"), and more than one belly button ("Pit of Despair"). They have a little bit of hair on top of their head. Typically, they sleep very little. They are known to be vile and violent, wreaking havoc ("Wanda's Wand"). They also usually take things literally, and do not use the same ways of measuring time as humans do ("Three's Company"). They can have dreams ("The Search").
'Monster' is considered a derogatory term by Gahroos and they do not like to be called that.
Gahroos are the only known species that can survive a beheading, and through magical means, reattach a head from the separated body. If the body is not reattached, the head can grow a new body. This takes a couple of years for a full-grown adult to do, and while the regrowing happens, Gahroos sleep quite a lot, up to fourteen hours per day ("Children Will Not Listen"). They can also go for long periods of time without eating, as Trexel the Terrible mentions having not eaten in a week ("Blumpkin & Felchy").
Gahroos believe there are many gods. They know of the multiple dimensions. They also have complete gender equality ("Daniel & Grezit's Crazy Christmas"). It is unknown if all Gahroos make specific, graphic threats of their opponents, but at least Grezit and his mate, Trexel, do.
