Arceus is never in the Ice Cave.
You trade an arceus over from another game, then put arceus in the day care with ditto. talk to the day care man and he will ask if he should call you if he finds an egg. Accept and go up and down goldenrod city. When he calls you talk to him and voila, an arceus egg. P.S. you can do this with any other pokemon and ditto.
You need the movie arceus or a regular event arceus for heartgold or soulsilver
On Pokemon Heartgold, the blue orb isused to summon Kyoger at Embeded Tower in a cave near the Safari Zone. I hope I helped! Have a great day!
the next event is the arceus event the day Pokemon 12 the movie comes out. you know the one about arceus.
saturday.
by friendship in the day
yes. at Pokemon day care if they have to same egg group.
You can get it in the Safari Zone, near the Day Care or at Cerulean Cave. . ^_^
put it in day care with a ditto
Espeon: Evolve at day Joteon: Thunderstone Vaporeon: Waterstone Flareon: Firestone Leafeon: Leafstone Umbreon: Evovle at night Glaceon: Evovle at ice cave (i think)
dunno about heartgold, but in soulsilver it is in that area of grass under the day care and you have to headbutt to get him too.
