Multibonk
Multibonk is a move used by both Goombario and Goombella in both Paper Mario games. It uses up 3 FP, and can be used once Goombario is Ultra Rank or Goombella is Super Rank. When using it, unlike the normal Headbonk, the partner will keep on striking. The first strike will do the same damage as one Headbonk, and each consecutive hit will do 1 less damage than the one before, to a minimum of 1. The cycle will continue until the player fails to hit the Action Command. Multibonk is nearly identical to Mario's Power Bounce attack.
Goombella's Multibonk includes two opportunities to perform Stylish Moves: one before she jumps (as with Headbonk), and one when she is halfway to landing the first bonk.
Multibonk can become extremely powerful when Goombario/Goombella Charge it or use the Charge P badge's effect multiple times; it will significantly increase the attack's power.
