Nidorina, Nidorino, Clefairy, Jigglypuff, and Skitty
yes in route 3 and 4 and the safari zone but its kind of uncommon
Pokemon Heartgold and Soulsilver allow the first Pokemon in your party to walk with you. You can talk to it and find out what kind of mood it's in.
Depends what kind of pokemon. Most evolve by leveling up, some using stones (firestone, moonstone, etc) some by trading, and some by trading holding a specific item.
Moonstone is kind of gems and is used in jewellery prominently.
With some kind of pokeball. Maybe you should have asked how to find/get to ho-oh instead and not how to catch it.
You are kind of asking if you can trade a certain Pokemon. My answer... WHY NOT? If you meant were you can find Phanphy, then you can catch the evolved form, Donphan on victory road and on the route to Mt. silver.
Poliwag can be caught by using any kind of rod in Route 43 (Pokémon Heart Gold / Soul Silver)
You can capture it in the safari zone but it's kind of rare.I don't have all info but some pokémon sites probably says how to make it happen.
you have to follow watching your map on pokegear. eventually it will let u battle it instrad of it keep moving. kind of like one of the 3 Pokemon on diamond/pearl
Poke Flute Just a radio channel that only Kant uses Black Flute Repels wild Pokemon White Flute Attracts wild Pokemon Blue Flute Awakens a sleeping Pokemon Yellow Flute Snaps a Pokemon out of Confusion Red Flute Snaps a Pokemon out of Infatuation
