A Lot Of Pokemon Trainers Have Happiny But You Can Also Get A Happiny In A Hearthome City There Is A Hiker Who Will Give You An Egg,And Inside That Egg There Is A Happiny.
Happiny is a Pokemon from the newest generation, Diamond; Pearl; Platinum. So you cant get happiny in Sapphire
You can get happiny in the trophy garden.
If your Wigglytuff/Jigglypuff (which are you saying?) is a male, then yes, you can. :) However, you will get a chansey or a happiny (if you give your chansey an odd incense), and not an igglybuff.
Happiny can be recruited in Happy Outlook.
Happiny is a 4th generation Pokemon none of those Pokemon existed in previous generation games like leafgreen.
You can't in this game, it's only allowed in Pokemon Yellow, and Pokemon Heartgold and Soulsilver. If you mean walking in the park in Hearthome City, you need a cute Pokemon like Happiny, Drifloon, Pikachu, or Clefairy. There are more, but I don't remember.
