A dinosaur-like creature with circular saws imbedded
in its head and tail, hence its name. It was scrapped in Season 1, likely due to its rather scare potential.
Candy Floss was actually to appear in Season 3 had it not been cancelled, likely to replace Lady Illusion as Lord Fear's female minion. Concept art shows her in as a punk rock/punk goth/goth rock archer firing lollipop-shaped arrows. Rick Siggelkow provided more details on her after the show ended.
- The Archer
- Goth Rock: She is dressed in a goth rock/punk rock/punk goth appearance. She has a mohawk of sorts, wears a helmet, a bra under a jacket, shorts, striped tights and platform boots.
- Improbable Weapon User: Candy uses lollipop-shaped arrows...which explode! She can also ensnare enemies by tying them up in candy floss.
A quintet of unnamed minions which disguised themselves as stuffed animals to hide in the carnival and spy on the Lightning Knights. They were scrapped, and their stuffed animal aspect went to Dirty Rat. Poor fella.
