The young, philosophical Goyat, about ten ape years old, has recently known that Naoki and his wife Sayuri abandoned him and his slightly older sister Malagasha when they were young kids. They were now in the pretty awful custody of their new supposed temporary guardians.
He isn't faithful to his guardian either, but he does care about much of his community being screwed up. Then he saw him net up Tarzan, just to his own chargrin!
Malagasha, now twelve ape years old, is sure that she must rebel against both parents, even if the mum murders him up by the ass.
