Metroid Mania (メトロイド オモロイド), formatted as Metroidmania in PAL regions, was a Spirit Board event focused on Spirits from the Metroid series. It ran from 6 a.m. on June 28, 2019 to 6 a.m. on July 1, 2019 (UTC). During the event, defeating Spirits on the Spirit Board which were part of the event was supposed to award more SP than usual. For unknown reasons, some players were awarded additional Gold instead. Notably, the previous 2 spirit board events awarded additional Gold, suggesting that it may have been a rollover bug.
