Posie

Posie is a flower that lives in Flower Fields during the events of Paper Mario. She lives under the Crystal Tree, a tree that produces Crystal Berries. Posie is very protective of the Crystal Tree. She provides Mario with the Fertile Soil needed to reach Cloudy Climb.

The Crystal Tree's roots are connected to Posie's, so when Mario whacks the tree with his Hammer, Posie can feel it. If Mario hits her tree too many times, Posie will kick Mario out of her area. If Mario walks back in, Posie will yell at him to get out. It's not permanent; return to her area five times and she'll eventually cave in. However, if Mario keeps hitting her tree, she'll keep kicking the plumber out.
