From the publisher: “What do two platypuses, a mad scientist, and two dogs have in common? Well, not much actually, but somehow we did all end up at Cucumbery Corndog’s totally secret base practicing yoga together. Why, you may ask? Well, I guess you'll just have to read this book to find out, but I can give you a little hint. It has something to do with mentos, Diet Coke, a jar of peanut butter, and a whole truckload of bananas. Did you know that platypuses love bananas? Yea, I didn't either. - Buddy”
