Plant Boss: Did the Golden Finger Run Away at the Beginning?

Traveling through another world, I finally waited for Goldfinger, but Goldfinger ran away? Fortunately, this golden finger was kind enough to leave him compensation. It's obviously just a hard iron tree, why did yours explode? They are obviously just flowers for viewing, so why can yours replenish the blood of others? They are obviously just mushrooms for eating, so why are your mushrooms poisonous?
