Uh oh, Chinta the Baby Chinchilla is lost! She's hanging on a tree branch over a river and could fall -- and chinchillas don't swim! Diego transforms Rescue Pack into a hang-glider and flies down to catch Chinta just before she falls in the water. Now Diego has to get Chinta back to her family on Chinchilla Mountain. First they jump through the cactus field to get away from a puma, then find their way through a dark cave by using Chinta's sharp hearing, and finally hop up Chinchilla Mountain singing the 'brinca' song.
