Years ago, Dr. Muretta, as a young scientist and scholar of witchcraft, made regular explorations to a remote section of the Brazilian rain-forest. Her studies in the "Dark Arts" fueled her search and exploration of ritual artifacts from native tribes. On one of her many visits to the region, she befriended a playful spider-monkey she soon called, Jaja. It wasn't long before Jaja become a permanent addition to Murreta's expedition crew and a faithful pet.
