That sounds like a scheme Wile E. Coyote would come up with.
I can visualize it – and the inevitable outcome
(It’d probably be a mechanical kangaroo. Long after he set it hopping, at the end of the cartoon, after we’ve practically forgotten about it, he would turn away from the ruins of his previous scheme and suddenly be unexpectedly confronted by his Hopping Doom, and would just have time to realize what was about to happen when it blows up. After the smoke clears we see a blackened, frazzled coyote. He looks directly out at the audience for a beat, then holds up a sign reading Tell Them to Put a Shrimp on the Barbie for Me. Iris out.)
Small tip here. Kangaroos sure look cute. Try and get hold of one, and I guarantee you will get the sh!t kicked out of you way before you get anywhere near putting things in pouches etc.
