Volcano Island - S1.E38

While Kimba takes the children at school on a field trip to Volcano Island, Boss Rhino is busy there trying to make way for a female rhino that's about to give birth. Boss Rhino demands that Kimba leaves, but when Kimba refuses, he is forced to accept Boss Rhino's challenge to a match. The two fight, and both end up equally injured. Neither of them wanting to give up, they both agree to "postpone" the match the other has recovered enough to fight. Though they refuse to admit it, it was a draw. Soon the baby rhino is born, but when the volcano erupts, Kimba and Boss Rhino must set aside their differences and work together to save everyone.
