Noah and Gertie go back to Africa to find a mate for the Valve Rhino, but because the Rhino has charged off into the forest, they ask Gorm to push the valve system in the Fire-Bowl. The Rhino wanders into Queen Abront's cave, and Rocco and Woomera venture in to find him, but get lost in the tunnels. Meanwhile, Galleo eats the lice Sacha was collecting for his insect circus, so Sacha believes that a monster is on the loose and sets out to find more lice.
