Things I’d prefer my children not repeat.
Format: Hardcover
My kids found it entertaining, but as a parent I was not thrilled with all the “poop” and “fart” jokes, as well as characters belittling and calling each other “stupid” and “butthead.”

Funny and clever
Format: Hardcover
Sashimi, a fish boy, is trying to find someone just like him. Instead he finds unlikely friends. The book is very funny and clever with just the right sense of humor for kids 2-100. I won my copy from a Goodreads giveaway. I will be sharing my copy with my grandchildren who will fall in love with Sashimi, too.
