Barbell

Barbells are objects that appear in Donkey Kong (Game Boy) and Mario vs. Donkey Kong 2: March of the Minis.

Donkey Kong (Game Boy)
Barbells appear in Donkey Kong (Game Boy) in Stage 9-9 during the final battle against Donkey Kong. When Donkey Kong slams the ground, barbells and barrels drop from above. If Mario is hit by a barbell, he loses a life.

Mario vs. Donkey Kong 2: March of the Minis
Barbells appear in Room 1-DK in Mario vs. Donkey Kong 2: March of the Minis, dropping along with barrels when Donkey Kong slams the ground. They behave identically to their previous appearance. If a Mini Mario comes into contact with a barbell, the Mini Mario breaks and the barbell disappears.
