Well now I have to decide who wins my contest. After a lot of deliberation I realized that the one that I found myself envisioning the most readily was  jimox1985's suggestion, for 2 reasons:

* In my imagination, he's trying to trade me a dandelion, with the roots dangling off with dirt on them and everything ... and it's obvious he just pulled it out of the ground ... and there are a bunch of other ones all over the place so I could easily have gotten my own. Hence my look of not-impressedness which I hope will make the whole thing super funny. I mean hey, it's not unreasonable; I've seen bunnies eat dandelions. Eat all you want, bunnehs! Eat 'em all if you can!
* He suggested an Oreo cookie, which would be very recognizable as such when drawn. Especially if I've got one of those giant Oreo Big Stuf cookies that they haven't sold for several years in RL, but this is art!

So congrats to Jim, and I'll get to work finishing this drawing finally! Thankoo to everyone for entering: Jeyne, Jim, Yuki, Shido, and Doxie, Marcus and Cain, Sarah, and Jimmy!
