Question: where to find ditto in pokemon yellow?
Answer: Locations: Ditto may be special, but it's actually pretty common. You can catch this shape-shifting blobon Routes 13, 14, 15 and 23 as well as the Unknown Dungeon in Pokemon Blue/Red. Pokemon Yellow players won't see it as often, but they can still catch it in the Unknown Dungeon, as well as the Pokemon Mansion.
