-Rhyperior for HG. I think you can get Rhyhorns from the Safari Zone. However, you hit its head when you threw rocks at it and it thinks it is Palmer's Rhyperior from DP. Palmer's Rhyperior know Flamethrower, Ice Beam, Thunderbolt and Rock Wrecker, has an expert belt and has Solid Rock. This is what your Rhyperior has to copy, although to save you days at the Game Corner, you may use Fire Blast, Blizzard and Thunder instead. (from athenodoros)
-Catch a Hoothoot named Shiny. It can only use moves that Ash's Noctowl used. Once it evolves, it can't even know any moves unless Ash's Noctowl used them. After viewing every TV in Johto with Shiny in your party, change its nickname to Forisia, it can hold any item it wants, and it must learn one move that Ash's Noctowl doesn't know. (from auramaster)
