In the spirit of Mo Willems and Ben Clanton, this charming, laugh-out-loud picture book shows how a good friend can become even better by trying new things and putting others first.

Cat and Duck are very good friends and play together all the time, so when the new slide gets built, they can't wait to try it out! Only, the slide is very big and curvy?what if it's too big for Cat? As Cat and Duck move closer to the front of the line, Cat imagines everything that could go wrong until his worries start to rub off on Duck. Now Duck doesn't want to go down the slide either.

Cat feels bad that Duck is missing out on the fun because of him. Can he find a way to make it right?
