Here's an ending that can bring loads of luck.

On the last day of the month, a wave animation will come cross the screen and reveal the lucky days. Even if you played every day, some days will 'wash away' and the lucky days will be left. 

The lucky days will have prizes allocated to them. The more days you cover, the more chances you have of hitting the lucky days and thus getting a prize!

Blue Shells will displayed on the lucky days that you played Tiki's Catch of the Day, and Seaweed will show for lucky days that you didn't play. If you have a Blue Bell on a lucky day, click on it to reveal your prize and remember to check them all!
