 * Attack of the Tetriminos! is the first Spirit Board event released after the version 4.0.0 update to be followed by another Spirit Board event rather than an Event Tourney.
 * Attack of the Tetriminos! is the first Spirit Board event based on a non-playable universe to come with more than 4 new spirits.
