Bowser Jr.'s Bonk Battle
From the Super Mario Wiki
Bowser Jr.'s Bonk Battle is a Bowser Jr. minigame from Mario Party 10.
While Bowser Jr. is standing atop clear blocks, the player is standing just below them. The player must hit these blocks from below to hit Bowser Jr.; every successful attempt deducts one of Bowser Jr.'s hearts. If the player deducts all three of Bowser Jr.'s hearts, then he/she wins; otherwise, Bowser Jr. wins.
