Hoenn had too many Water/Ground types (Barboach and Mudkip lines) so they swapped the Shellos line for Chimecho. That's just my theory, but it makes sense. Masuda already confirmed Shellos and Gastrodon were supposed to be Hoenn Pokemon. Chimecho is also the last Pokemon by index number in RSE (excluding the remaining Unown forms), coming after even Deoxys. Chimecho is also only found in two patches of grass in Mt. Pyre while Chingling and Chimecho very common in Sinnoh. No one would look at Chimecho and say "this shitmon is too strong, it needs a baby form next Gen," so Chingling and Chimecho were likely created around the same time. Bronzor and Chingling lines are both idiophones found in Mt. Coronet.
