Valentine's Day has come and gone, and a lot of video games are still celebrating the holiday by holding special Valentine's Day-themed events. That includes Pokemon Go, which is set to wrap up its own Valentine's event, meaning players only have a limited time left to capture some very rare pink Pokemon and earn extra bonuses.

For a few more hours today, February 15, Pokemon Go players will encounter increased spawns of the heart-shaped Pokemon Luvdisc, one of the many Gen 3 Pokemon that were recently added to Pokemon Go. Chansey will also appear more frequently for the duration of the event. Players will be rewarded with triple the usual amount of Stardust for each Luvdisc and Chansey that they catch.
