August 13th, 2018. One of the rarest event on our planet is about to begin: Fertility Day. Once a year, Seafront ocypodes rush out of the shallow water of Helodrano Bay and look for a partner in an unusual courtship ritual. Males must build a powerful sandcastle in a race against the rising tide to have a chance to be selected by a female!
It is the very first Fertility Day for Eustache, and failure is not an option. Fertility Day only happens once a year, it is his only chance to impress Hexa and he will not miss it. Grab your mouse and your keyboard, it is time to help a crab in love and build faster than the incoming sea!

Curious about Fertility Day? Follow this link to have a better understanding of Eustache’s past and the life full of danger of Seafront ocypodes.
