Hercules, guardian of the Lemuria Zoo, has a big problem: the Zoo's divine animals have been going crazy. To make things worse, Queen Louhi, the CEO of Gods Incorporated, has just arrived for her yearly visit... with a new fianc in tow (along with his yenta-minded grandfather Jupiter). Of course, the fact that Hercules is desperately in love with her doesn't help his plight in any way whatsoever. His attempt to cover up the situation quickly blows up in his face and they finally realize the animals' madness is caused by artificial means. Cue in the bodiless god Mimir, who reveals that the real target of the mind-altering poison is Yggdrasil, the World Tree. And if the Tree loses its cohesion, then so will the barriers between the worlds, crumbling the foundations of reality. Who in gods' names could be crazy enough to want to do something like that?
