Ditto is a special Pokémon that has no level requirement and can be bought at Diamond Shop. The special ability of Ditto is Transform, which allow Ditto to transform into other Pokémon.
To transform Ditto, you should use the Order button in another Pokémon. If you want to reverse the transformation, use !revert.
The Shiny Ditto has better status and the time is longer than the common Ditto transformation, and can be transformed into Shiny Pokémon.
To check the remaining time of transformation, use the command: !ditto.
