They seem to be breedable with the Lucky Clovers.Lucky Clovers themselves are breedable with the white clover, which are obtainable all year round. Or at least, the white clover USED to be obtainable all year round; I don't know if that's still the case.
Oh, good, I have some of those! I'm hoping to breed mine, if it grows up in time!
So, Tempest, you could breed both of yours then, right?
