There is a $100,000 reward for the capture of a rare beast; a kangaroo/ape hybrid called the Kong-aroo! Yang wants to find the beast for the money, while Yin wants to help the creature protect itself from other hunters. But when Yang's competition is Carl, and Carl is even more determined than usual to get his way, can Yin and Yang prevail against him?
- Yin ang Yang's Safari Suit appears in Pets Peeved, before this episode airs!!
- This episode marks one of six episode where Yin, Yang and Carl joined allegiances. The other five were Pros and Cons, Dictator of the Year, Night Fall, Deja Foo and Welcome to the Dark Tomorrow. The latter two episode are because of alternate realities.
- The episode title is an apparent parody of The Call of the Wild.
