use the galaxy shroom on peach and mario before you attack her. also start off with a chaos grenade from someoen who is equipped with a spped bracker. You get spped bracker for winning the game vs fake mallow when he is trying to peck you to death in nimbus land. Also getting 3 diamond mail to work from the random battle in the sea from the invisble monster (I forget what they are called but its the first room you enter after you fall down. It helps to have the battle mania from beating the shy guy at booster way to have 3 times as many chances. Keep battling until you get 3 diamond mail. I owuld also try to have a magic ring on mario as well and use his ultra flame on the enemy when you are trying for golden flower. Golden flower drops will be rare also so save before the battle and do save state abuse if you want. I will not lie I have done that to just move things along.
