This is a key aspect in an event match on the stage, as the flower must be sprouted while avoiding Olimar's attacks as Peach to clear the event and unlock Hanenbow. When all the leaves on the right-most tree are a dark red, a flower sprouts on top of the tree, making another sound effect.
Note that the branch on the left can't be stood on (although it serves as the Pokémon Trainer's platform). Additionally, leaves will straighten out over time, returning to being horizontal. Over time, the leaves will return to being green. Attacking the leaves will also shift their color from green to yellow to red. The platform's angles can be changed by attacking them. It also features the Hanenbows being fired at the stage's platforms, which make a musical note on contact depending on the angle of the platform. The stage consists of multiple stems with leaves branching out on each stem.
