The first week they served the food put in plastic clamshells designed to look (kinda) like the space crafts on the show. The blue one was the Inceptor. The grey one, the Commander. The green one was the Iron Falcon, the bad guys' ship. Each came with stickers so you could put the various details on the ships; stripes, decals, people in the windows, etc (I only put the stickers on the green one, I dunno why. Ruin collector value?). Rawlins and I worked in lower Manhattan at this time and there was an actual Roy Rodgers restraint by us. We would meet for lunch and each order the kids meals, so we could start collecting the pieces for ourselves (and maybe raise awareness?). And yes, we were the only people in lower Manhattan ordering kids meals. Then in the evenings, I'd drive to the one by my house and get dinner there way too often to get more stuff.
I have several of each, but only 1 gray top. It's an even number of tops and bottoms, so I don't know what happened there.
