Fun and imaginative read-together stories
Format: Hardcover
Doodle Champion Island Games is a 2021 interactive role-playing browser game that features a character called Lucky the Ninja Cat who competes in various sports-based mini games, loosely based on the 2020 Summer Olympics and Summer Paralympics. Kitten Ninja is a marvelously illustrated book that features Ninja Cat as a kitten when he battles a sun spot, a ball of yarn, and snow. At the end of each battle, he is happily in the lap of his owner as they relax in her overstuffed chair. The quality and durability of the book is excellent, with bright colorful images and well-written text. This is a delightful book for a parent or caregiver to enjoy with a pre-school child or one that is learning to read, or a special gift for a young child who is learning to read or reads at grades 1 through 3 level.

Great bedtime book.
Format: Hardcover
This review is for: Kitten Ninja This is a cute little hard cover book. It's not a large book, so perfect for a quick night time read before bed. It contains three cute stories. Perfect for anyone that owns cats and knows their antics. Battling yarn, snow, etcetera, Kitten Ninja always comes out on top. I think this is appropriate for any little one, probably up to age eight or so. Now that I know that this is a prequel, we will have to check out the other books in this Epic series.

The drawings were cute and funny.
Format: Hardcover
Kitten Ninja is a cute graphic novel for young readers, who love cats, and mischief. The Illustrations are adorable and well done, capturing Kitten Ninja battling it out against his enemies. The writing is easy to read and fun. Three short but entertaining stories about Kitten Ninja, as he faces off against his foes, the Spot, Ball of Yarn, and Snow. Here is what my eight year old thought of Kitten Ninja: "It was good. I liked it, and thought it was funny. The drawings were cute and funny. Kitten Ninja vs The Spot was my favorite." Kitten Ninja is perfect for fans of "Pets Rule!" books, "Bad Guys" books, or "Bad Kitty" books; and is the prequel to the "Cat Ninja" books, in these cute but funny tales. 5 ⭐ out of 5⭐ definitely recommend.
