When a tribe of Sasquatches flee from a mysterious curse, they take refuge in Hugo’s home, Widdershins Cavern. These new Sasquatches look a bit . . . odd. For example, they all have unicorn horns on their heads! Always open to meeting new creatures, Hugo befriends one of these strange squidges, Nobb. Nobb offers to escort Hugo though the North Woods so that Hugo can attend Boone’s birthday party. Having never been inside a Human house, Hugo finds the experience confusing and somewhat disastrous. Just when it looks like Hugo may have ruined Boone’s birthday, they set out on a mission to solve the troubling curse in Nobb’s cavern.
