Pokémon’s 25th Anniversary is right around the corner, and for “Pokémon Day” — February 27, the release date for the original Pokémon Red and Green in Japan — Pokémon is hosting a virtual music concert in celebration, and it’s being headlined by none other than Post Malone.

To coincide with this concert, The Pokémon Company International will distribute a Mystery Gift code unlocking a special event Pikachu that knows the move Sing, a move which can’t normally be learned by Pikachu. This distribution starts on February 25, 2021.
