This short is on a DVD box set, "Walt Disney Treasures : Mickey Mouse in Black and White: Volume #2," and I bought it when I was on vacation with my family. This short became one of my favourites out of the collection; I thought it was "bouncy-touncy" fun.
It all started when Mickey received a package crate from an Australian named Leo Buring. And to his (and Pluto's) surprise, the crate started jumping around, and then SMASH! Out jumped a boxing kangaroo and her joey. I knew it was a female because the males don't have pouches. Anyway, Pluto did not like the idea of that "grasshopper" and her kid invading his premises. You know, we get to hear his thoughts voiced by Pinto Colvig, who also does his barks and pants. I noticed the kangaroo and joey are drawn the same way as Mickey, and also that the joey almost sounds like Roadrunner from Warner Bros.
I love it when Pluto chases the little hopper; he gets wet thanks to the joey hopping on the giant water pump. Then Pluto goes for a rough ride in a wheelbarrow and lands in a garbage dump. With his back paws stuck on springs, Pluto bounces up and down to the little kangaroo's delight. They hop for a little bit before Pluto hops a little too high and smashes head-first into the roof of a greenhouse. Pluto is unaware that the little kangaroo has become attached to him by resting in a corset "pouch" that he jumped straight into from a clothes line before the greenhouse. A bit of risqué business, huh? Overall, this is a great cartoon, and now I have gone "Kanga-crazy!"
