Skeeter (New Super Mario Bros.)
From the Super Mario Wiki
Skeeters are large-bodied magenta versions of the enemy of the same name in New Super Mario Bros.. They only appear in two of the game's levels, World 3-A and World 8-2. They skate aimlessly across the surface of water, dropping blue bombs drawn with white skulls. The bombs can destroy blocks, giving access to some Star Coins as a result. They and their bombs release coins upon being hit with a fireball from Fire Mario.
