What does the piranha plant capsule do when you use it on yourself in Mario party 5?

In Mario Party 5, using the Piranha Plant capsule on yourself allows you to summon a Piranha Plant that can attack other players who land on the same space as you. When activated, it will bite any opponent who enters your space, causing them to lose coins. This capsule serves as a defensive strategy to protect your coins and disrupt your rivals' progress.
