This fiction picture book tells the story of Tiddler the fidgety fish. He is a child fish that cannot be still, so his mom sends him outside. She tells him to watch out for the big fish. Tiddler goes out and has a grand time until he is swallowed by a big fish! He is burped back out thankfully, and after that, he went home and went straight to bed because he was finally tired. I enjoyed this book because I love under the sea themed illustrations, fish are fascinating with all of their colors so I was attracted to this book immediately. I like that Tiddlers mom gets fed up with him and sends him outside to use some of his own creativity. If I taught a kindergarten class, or even preschool, I could use this book as a read-aloud and then have the kids use their "energy," to go outside. I would have them find something on the playground that resembled being swallowed by a big fish and the burped out again and they could each act it out for the class. I assume they would choose something like a tunnel slide, but there are no wrong answers. Then I would have them come back inside and settle down for a nap, just like Tiddle's mom did.
