The Floro Sprouts ultimately control their victims, but their effect is different on different people. Controlled Cragnons completely obeyed the Floro Sapiens that used the Floro Sprouts, and would even die for the Floro Sapiens while possessed. When Luigi was controlled by a Floro Sprout, he still had slight control of his hand movements, trying to break free. When O' Chunks was controlled by a Floro Sprout, his battle strategy was improved and he got even stupider. O' Chunks, now called O'Cabbage when controlled, could only shout the names of vegetables. The will of the victim may have some role in determining how well the Floro Sprouts control them.
