- Ho Yay: Yoyo and Doc Croc have their moments together. In one episode they skinny dipped and in the Nightingale episode, Yoyo actually kisses Doc Croc on the lips.
- Jerkass Woobie: Constance in the King Thrushbeard episode. She's a manipulative Rich Bitch and her father is forcing her to marry someone she doesn't want to.
- The Woobie: Doc Croc at times, mainly cause of his nervousness and stutter.
- They Changed It, So It Sucks: The third season, which dropped adapting only Grimm stories, and features noticeably cheaper animation. It also never got an English release, due to having been a French co-production (the first two seasons were an American/Irish/German co-production).
