This gift was distributed in Toys "R" Us stores across the United States, distributed to commemorate the release of M08: Lucario and the Mystery of Mew. It has been determined that 430 MYSTRY MEWs existed, though only 426 was used, and 4 were not available. This extra 4 was created due to how the distribution procedure (when transferring to the save used by TRU) has to create 5 Mew at a time. This page holds the MYSTRY MEW that was available to players.
