Mickey and Pluto makes a short stopover on a South American flight. Mickey throws Plutos ball into the jungle, and he chases it but it looks exactly the same as an armadillo thats rolled up into a ball. This, of course, greatly confuses Pluto for a while. But he eventually makes friends with the armadillo. He chases the critter into a cave right behind his ball, and rips the ball apart thinking its the armadillo, which makes him very sad until the armadillo shows up again.
