Quote from Eevee:
Give it a whirl and tell me how I screwed it up this time.
The breeding chain finder is a good million times better, but still not perfect.
Take, for example, Bulbasaur and Sludge Bomb. It comes up with (assorted poison pokemon) to Gastrodon to Corphish to Skorupi to Paras to Bulbasaur. Thankfully, I won't have to waste my time breeding, because such a chain is impossible. Sludge Bomb can be TMed to Gastrodon, but not to Shellos. Therefore, Sludge Bomb cannot be bred into the Shellos family.
I'm not sure how much of a nightmare this will be to fix. Whatever method you use in the Pokemon Search to return Baseform pokemon might work, except for things like Mantyke/Mantine, where you can produce an egg of either one.
oh tjord now i can't not have a signature
