Do you think Carter likes Lightening McQueen? I believe this qualifies as "slightly" obsessed. I know for sure two others aren't in the picture. Who's knows how many we actually have. The two in packages are what he picked out this week for potty prizes.
And yes, he plays with all of them and notices if one is missing. The two that are not in the picture are actually Evan's hence the reason we haven't launched a massive search and rescue. As long as Carter's brigade is all accounted for all is right with the world.
Apparently, there are like 30 others that we don't have - so shhhh don't let Carter know!
