The island across from Playa del Carmen is called Cozulmel and on one of the days were in Playa my mother kidnapped me and dragged me onto a boat.
Until this point, the weirdest buskers I had seen were bagpipers. Those seem somewhat normal now, compared to the marimba player.

In port.
We looked up these little guys on the internet and never could pronounce their name so we simply called them "critters" for the duration of our trip.
