Hammer Chime

Hammer Chime is a boss minigame against Hammer Bro. in Mario Party DS. Its name is a pun on "Hammer Time".

The main idea is to follow the pattern. Hammer Bro. will hit four colored drums in order, then release a music note to attack the player. Using the stylus, the player has to play the same drums in order before the music note hits them. If the player doesn't hit the same combination in time, they will lose a life. If the player manages to play them on time, then the charged Music Note goes back and hurts the Hammer Bro. and he will lose a life. After three hits, the Hammer Bro. vibrates slightly from the shock of the last strike, and collapses. The player wins and clears the board challenge on Toadette's Music Room. They are also awarded Toadette's music chair as a trophy.
