I like the story-within-a-story format. When the toys are left outside, some of them feel afraid. So WonderDoll tells a story to pass the time, one where the toys all go in a space ship and of course come home safely. Very kid-relate-able, and the way Grey used the space on the page to tell her story and the story that's told within it was clever. I'd hoped for a funnier twist with where the alien's lost toy was, so the ending wasn't as satisfying as the rest of the story, but still, this was fun.
