First appearance: Hvs.tCF 71
They were first mentioned by Jed the Head as a potential substitute source for Knights after the defection of the Knights In Stanley's Service to Charlescomm. Presumably Juggle Elves can function particularly well as Infantry, Knights, Lancers and can Rock Out alongside Stanley.
They're very different from all other varieties of elf in that they're much more like Hobgobwin's in appearance and demeanor. They use Signamancy spells from Shady Elves, Scene Elves, and Navy Elves to leave their faces permanently painted.
Real World References
Their name and Signamancy is a reference to Juggalos, the fans of horrorcore band Insane Clown Posse. Their favorite drink, Fae-Go, is likewise a reference to Faygo, a local soda made popular by ICP. Fae is an alternate spelling of fey (relating to elves, as in "faerie").
The elders of the tribe are Chief J and Shaggy, named for ICP's Violent J and Shaggy 2 Dope.
