Pip = Leia. LOOT Bag = Han?All analogies break down eventually.
I think Pip is metaphorically or rhetorically speaking to Kitteh.So that works a little better.
Regardless of the references, if it doesn't work for Kitteh and Pip, it doesn't work. So what nefarious scheme does Kitteh have that leads him to carrying leaves around?
There's always the possibility that Pip added the leaves in teh heat of teh heist.
