Mythical Island, released in September 2022, is the exclusive habitat for Mythical Monsters. These monsters, initially unique to the Playstation Vita, were incorporated into the main game in 2019. The island allows players to breed Mythicals from the Natural and Fire Islands with Cataliszt, the Dream Elemental, to produce Dreamythicals. Although Rare Mythicals inhabit the island, they cannot interbreed with their common counterparts due to the island's breeding rules, which necessitate a pairing of Cataliszt and a purely Mythical Element monster.
