Death Bunny!

Thousands of years ago, Lord Devi, one of three rulers of the Underworld, became greedy and tried to gain control. A battle ensued; Grim the Reaper was victorious and imprisoned Lori Devi for eternity. That is until Kitti, a three-foot, eleven-inch bunny, unwittingly releases the demon while on a school field trip to the Museum of Boring Artifacts.
As the three-horned Lord Devi emerges from a red and black tomb shrouded in chains, Grim the Reaper, Kitti's adoptive father, battles the demon once again. Grim loses his grip and is sucked through a portal. Lord Devi declares victory and disappears. Kitti, also known as "Death Bunny," vows to rescue his father and defeat Lord Devi.
Kitti is aided in his quest by a host of quirky characters. There's Pandy, the fudge-loving panda bear; Zorg-10, a ten-foot robotic creature; Kurri, a giant caterpillar who undergoes metamorphosis; and Zom B. Me and Zom B. She, two zombie skeletons. Together they battle a malevolent bounty hunter, armies of demons, and a giant dragon monster. Will this band of faithful fighters overcome evil, return peace to the Underworld and reunite Kitti with his father?
