>>46597010Yes if the Pokedex is to be trusted, Goldeen are mentioned to lay eggs. However, if we assume the Pokedex is not perfect and filled in by people who don't know if its all true...
Well this is where things get a little weird, if Pokemon NEED to have a Male + Female to breed together (or Ditto) it implies there has to be some type of thing the two need to do to lay eggs. Personally I think it varies among the egg group. So the way two Grass/Plant Egg group Pokemon would have offspring is different from how two Human-Like/Human-Shaped Egg Group pokemon would reproduce. It might even go deeper than that and require special ritual via the species, but I don't know for sure.
