Fifth-graders Parker and Lucas get more than they bargained for when they seek to debunk one of Wolver Hollow's greatest legends about a haunted mustache that, every year on the anniversary of its owner's death, seeks a lip to claim as its own.

"A biracial Indian/Caucasian girl is nervous to begin middle school, especially since her mother is now the breadwinner of the family, her best friend may no longer be a bestie, and the appearance of the seventeen hairs over her lip that form a very unwanted mustache"--

A play date goes awry when Baby Billy and his mustache meet Beard Baby.

Mustache Baby and his first mate, Beard Baby, set out to be heroes on the high seas, but soon the lure of pirate treasure takes hold.

"When a mustachioed rabbit spots a mustache contest, he's sure he has the competition beat. That is, until a pesky frog hops up with his own fine mustache. And a duck waddles up with a...duckstache? Soon, the competition is full of moosestaches and mousestaches, whalestaches and tailstaches--and every kind of 'stache in between."--
