I thought this book was really cute, too; it’s something I could definitely see as an animated short. There are other Otto books that we’re looking forward to reading, but Toon Books are definitely something we’ll be looking for, regardless of the main character!
The TOON Books website has great resources for parents/educators as well as kids. Their book list is broken down according to reading level, so you can make sure you’re getting the best books for your beginning readers! Check it out at toon-books.com, but be prepared to spend a LOT of time exploring!
