Grimmar is cheery and cute, but she’s a dark witch with a bad attitude. 

And she wants to gain complete dominion over Wordth.

An all-around embodiment of evil, Grimmar casts a spell that scatters the Letterbugs to annihilate the Wordtrotters. She sends her Buggers to expunge all magical bugwords in order to crush the defiant Wordtrotters.
