Bomb Block (Mario vs. Donkey Kong 2: March of the Minis)
From the Super Mario Wiki, the Mario encyclopedia
Bomb Blocks are objects found in Mario vs. Donkey Kong 2: March of the Minis. They are somewhat similar to Pink Blocks – however, they can also be used to destroy breakable blocks. Once the player taps a set of Black Blocks, they can tap near the breakable blocks to drop a bomb, which can destroy them. They are found in Jungle Hijinks and can be used in this kit and Special Kit 3 in the Construction Zone.
