Yeah, Monsters In My Pocket was awesome.
At the height of MIMP's popularity, Pizza Hut ran a promotion giving away a single MIMP figure with a certain meal deal. I think it was with the kids' all-you-can-eat ('The Works'). I'm not sure about this, but I think the figure you got came in a miniature version of the regular MIMP package, which was shaped sort of like a McDonalds' Apple Pie package.
I love it when fast food chains give away real toys from real toy lines, instead of their usual crappy giveaways.
