"A Fraggle charm?" He rubbed his beak in thought, looking down toward Gobo. "Let's see... Fraggles are pretty rare, so I doubt there's one already existing since only like, 2% of anybody in the history of everything knows about you guys."

Seeing a bit of disappointment, he held up a finger with a grin. "Wait though, wait! I didn't say one couldn't be made. A singular enchantment can be done, it just takes some sort of information from the species being changed into. Generally that's study and a whole lot of written magic for 'plain' species or, in the case of demons like Fraggles, something to read and copy the magic."
