Arrr, Mustache Baby!Hardcover, 5 March 2019

Arrr, babies! Mustache Baby and his first mate Beard Baby set sail on the high seas and turn into big bad pirates in this newest addition to the popular Mustache Baby books! "Occasional badness has never been so good." (Kirkus)
In this swashbuckling tale, Mustache Baby and Beard Baby work hard to recover stolen treasure and convince baby buccaneers Captain Kid and Short John Silver to go legit. But when the scallywags refuse to play nice, Billy and Javier see red and go rogue, turning into bad guy pirates themselves. High spirits, plenty of pirate talk, and a mild message about not letting emotions get the best of you make for a rollicking read-aloud full of side-splitting, silly fun.
