Mambo de Battle is a in-battle theme in Mother 3. Like its name, it happens to be based on mambo, and a combination of an assortment of in-battle Spanish-based themes. The piece consists of trumpets, horns, spanish percussion, piano, and xylophones.

Mambo de Battle Plus

Mambo de Battle Plus is an extended and harder version. Extended parts usually have the same rhythm, but certain parts of the song that play 3 notes in quick succession must be hit accordingly. Unfortunately, whether it's an oversight or not, the player must press faster before those 3 notes start, often disrupting the rhythm completely.
