>>50809996The Chimecho line was probably always meant for Gen 4. The Bronzor line and Chingling lines are both psychic type idiophones native to Mt. Coronet, making them ideal counterparts. Chimecho in Gen 3 is only found in two patches of grass in Mt. Pyre with a 2% chance if I remember correctly. It's also the very last Pokemon in Ruby/Sapphire by index number (aside from Unown B-Z) We know they swapped out Shellos and Gastrodon because Gen 3 already had too many Water/Ground Pokemon. So they probably replaced them with Chimecho which was meant for Gen IV.
