Flower (Super Mario Sunshine)

Flowers are small pink flowers that appear in Bianco Hills in Super Mario Sunshine. They are always encountered with their buds closed to start out. As a yellow-green Pianta notes in Episode 1 of Bianco Hills (Road to the Big Windmill), Mario can water flowers using FLUDD, causing them to bloom and make a high-pitched singing sound. For single flowers, this causes the flower to dispense a single coin. Many flowers are found arranged in large rings, particularly in the later Episodes of Bianco Hills. When Mario sprays one of these with FLUDD, it blooms, but does not dispense a coin and closes its bud again a few seconds later. However, if Mario causes all of the flowers in a ring to bloom at once (done most easily using the Sprinkler Squirt move performed by rotating and pressing  with the Squirt Nozzle equipped), they all dispense coins at once.

Pokeys and Sanbo Heads have these types of flowers on their heads, and disguise themselves as them until Mario gets close (in fact, most rings of flowers contain a few disguised Sanbo Heads mixed in with the real flowers). Pokeys' and Sanbo Heads' flowers can be watered and bloom similarly to real ones, but they close back up quickly, do not sing, and never dispense any coins, which can help tip off that they are disguised enemies. Seedy Pods also have a yellow variant of these flowers on their heads, though they do not bloom when watered.
