>>46402180I'm surprised Jiggly/Wiggly haven't been knocked out already, same with horsea/seadra.
Zubat would require a common low level bat pokemon to be in the game to replace it in caves. Magikarp would require another useless fish to replace it for oldrod. Goldeen would require a slightly less useless fish to replace it for goodrod.
I see Zubat being the last holdout probably as there have already been bat pokemon that couldn't force it out.
