The Hammerhead Bros. are characters that appear in the game Mario & Luigi: Superstar Saga. The Bros. are named Sledge and Mallet and they are responsible for making and upgrading Mario and Luigi's hammers.
Sledge is the oldest of the two Hammerhead Bros. and he has been making hammers for years. His red facial features make him resemble Mario. He is also one of the wisest of the two.
Mallet is the youngest of the two Hammerhead Bros. and has been learning how to perfectly make hammers from his older brother. His green facial features make him resemble Luigi.
