A wallaby is what we want, so much better, plus smaller. It'll fit right in a backpack, just give it some food, they love grass, no not that kind shady, but feed him and throw him through the scanner at the airport they'll never know, considering some idiot can get 7 knives and a stun gun pass them I'm sure you can get one little wallaby. Your the man for this job shady!
