You already know what your first stop is. You head straight over to the marsupials and start looking for Kangaroos. Lucky for you, their not far. You find your first subject and pull out the remote. So how would this thing work, you thought in your head. You look to see there is a capture button on the remote. You distinctively remember in the instructions saying you have to "capture" the part of the subject you want in order to swap with it.
You aim at the Kangaroo with your remote and it's whole body inclosed with a glow. Than you adjust the glow to cover everything but the head. Than you aim the remote at yourself and your body starts glowing. You remove your head from the glow and remember you have to hit swap to initiate the changes. You press swap and the glow goes away.
For awhile, you don't feel anything, untill you see your clothes started to disappear. You watch as your body starts morphing into a kangaroo, from the neck down. You look back at the kangaroo you swapped with to see it getting thinner and wearing your clothes. You look down to see you still have your human head. But every else was a pure kangaroo. You looked back at the kangaroo to see it with your human body. You see the Kangaroo has no problem adjusting to your body as you see it hopping around like normal. You also seemed to still walk like normal thankfully.
You felt a lot of new sensations during your change. You start feeling everything on your new body with pleasure. You sported a huge smile feeling the huge feet, the thick tail, the big belly and... Pouch? You didn't realize you hit a female kangaroo and blush at the thought, but you quickly get over it enjoying your new body nonetheless.
You look around to see no one pays mind to a man with the body of a kangaroo. Your at least glad to see the toggle for reality alteration works. You than think of other swaps you would make.
