  • POW Block: Appears as a planar model above the opposing team and flattens itself for approximately 5 seconds before it disappears. Acts like a Banana, except it makes them lose their items if they are on the ground. Is very effective in dodgeball, as it can guarantee an instant win if used correctly. Only appears in basketball, soccer, volleyball, and dodgeball.

  • Banana: Can be placed onto the court. Causes the player to slip and fall. Can be used to block incoming shells.
