Woolly worries that a haircut might affect their reputation as the wildest and warmest mammoth around in this sweet and funny picture book.

Woolly loves their extra-long, extra fluffy, extra-unruly hair, and Woolly especially loves how it matches their wild personality. So, when they notice a teensy little snarl has formed, Woolly is sure it's nothing to worry about.

But little by little, with each rambunctious day, the snarl turns into a tangle, which turns into a knot, which turns into a BIGGER knot and soon enough it's getting in the way of Woolly's wild play.

Mama suggests a haircut could fix it. No, nope, NEVER. Not gonna happen.

But when the knot gets so huge that Woolly can't join his friends in any mammoth fun, will they discover that feeling your best is the first step to looking your best?

In the end, Mama helps Woolly see that getting a haircut isn't so bad and it even gives Woolly a chance to show off their mammoth personality.
