The park hosts a morning sing-off, and golden-cheeked gibbon Zoey introduces a new member of the family. Over in Hananya's group, hot potatoes are on the menu, and a fight among the female capuchins leaves Phoebe with a bite wound that requires surgery.

Mad Max meets his new housemates, and chimps Ben and Pip get a shock when they have another encounter with alpha-male Hananya. Piquita is the centre of attention in the woolly monkey enclosure, while Bart enjoys honey for the first time in Paddy's chimp group.
