The Best Episodes Directed By Jeremy Polgar

Lion-O wants to prove to the ThunderKittens that he's not just some boring old adult like Tygra, even if it means ignoring his instincts and messing with an obviously evil crystal.

Zulius brings the herd to Cataur Valley, where the shaman is fuzzy but fierce. To earn a piece of the key, Horse goes glam for a silly competition.

Horse meets Waterbaby — one of Centaurworld's shamans — and learns about the key: a mysterious object that could reunite her with Rider.
