Comb Gnomes are Duchess RavenWaves' henchmen, although they seem to have been recruted by Hairball. They are mischievous enough, but very lazy and can be counted upon to botch a job. Even so, they do have a magical attack that looks like lightning. These are usually blocked by the Pixietails, who use similar magic to create a shield.
The pink one is called Snags. He always talks in rhymes - which Hairball hates.
The blue one is called Tanglet. He can't talk, but only grumbles instead.
The purple one is rumored to actually be female, but "she" doesn't have a name.
