Difficult to tell, but that's a tiger, a scavenger hunt prize picked out by The Boy earlier this month at a friend's annual Independence Day shindig. He filled the cage up with water, was several times reminded that it would take a few days to grow into full tiger size, and tucked it in a bucket where other little toys are sequestered, out of the way and forgotten. Tidying up the other day, he pulled out the cage, tiger now fully grown, and was so excited about its growth you would have thought a living, breathing animal had actually made its way into the cage, instead of the bloated mass of whatever that material is, shedding murkiness into the water that helped it grow. Boy wants to attach it to his backpack. I rather like it on my shelf.
