Beaten Drum

Beaten Drums are enemies in Mother 3. While their default battle song is Tough Zombeat, they can change the song mid-battle to throw off a player's combos. When fighting against both it and the Jealous Bass, they can use a Jam Session attack, which is very powerful.

Battle Memory description
"Even after being torn, it defiantly orders not to give up, but to bang on the rim instead! It isn't easily beaten."
