They were all waiting to see if Yertle would show up.
The suspense was killing them.
We have a bin full of plastic animals that my son used to play with but instead of having them roar at each other and flying them around the house making monkey noises like most kids, he used to try to stack them like blocks. Except they don't exactly stack. He'd have to balance each one on top of the other very carefully. He figured out that he always had to start with the lion and then the hippo and then it was enough support to hold the cow, a kangaroo and sometimes the lamb on top. It was pretty incredible to watch.
These animals were inspired by our recent trip to the Jerusalem Zoo. It threatened to be a rainy and disgusting day so no one was there. Just us. Really. Maybe one other family. In the whole friggin zoo. The guy at the front let us in for half price explaining that half the animals would be inside because of the rain. In fact, it didn't rain. It was a gorgeous day. Most of the animals were out. And some of them were even stacked. OK, only the mosaic sculpture ones in the children's petting area. But pretty impressive nonetheless.
