Cookiesaurus Rex is the self-proclaimed King of All Cookies. Therefore, he deserves the best decorations that are available. When he sees other cookies being decorated fancier than him with stars, sprinkles, and gum drops, he gets jealous and tries to take matters into his own hands.
Cookiesaurus Rex turns himself into fun things, such as a superhero and a ninja. The child/decorator counters it by turning him into a clown and other funny things. It was entertaining to see what Cookiesaurus Rex would become next. It's the cookie form of dress up.
Final Verdict: This was an original read all about cookie fun and decorating. It's perfect for children 4 and older and something I could see being read while baking cookies to make it more interesting. Parents and children can bake their own Cookiesaurus Rex after reading it.
