Cinco De Mayo Week is a holiday event which is themed around the Mexican holiday Cinco De Mayo, which is celebrated on the 5th of May of every year (Cinco De Mayo means Fifth Of May in Spanish).

A special, limited-time Pinata Whistle is available for 5000 gems in the Growtopia Store during the event. It is a consumable which spawns an Ultra Pinata in a random place. During the week, Ultra Piñata event can also occur randomly without consuming a whistle. As of 2017, the Ultra Pinata no longer stays in a fixed position, but it can move anywhere around the world, including in blocks. This renders full dirt worlds useless. Players can receive various items listed below during the event:
