A while ago I was breeding a female
to a male
in my sapphire version, and the baby had thunderbolt and thunder -- two moves that were not in the Breeding Info part of its psydex entry. i think there are many more it can learn...
Also, breeding female
etc. produced babies that had Fly, Ice Beam, Rain Dance, and Double Team -- all moves not in its breeding info on its psydex entry (finally, a delibird that has useful attacks...not just Present...)
perhaps people could breed some pokemon and find more moves pokemon can learn by breeding? cuz i would find the info very helpful in the psydex
