An enchanted mole calling himself Phineas T. Headrush, or just Headrush for short, made his way from the land of Glum to New York City via Cudley the Cowlick. He appears in the comic Full Circle.
Trivia
Headrush is one of the relatively few characters created for a TMNT story whose rights are retained by his creator (in this case, Paul Castiglia).
