Bomb Sleigh

Bomb Sleigh (ボムスレー) is what its name implies--a sleigh with bombs. It appears in Freeze Man's stage and Wily's fortress stage 2 in Mega Man 7. It throws 3 bombs when it passes by, or when it is destroyed. Its weakness is Danger Wrap. Not only it destroys the bomb sleigh in one hit it also gets rid of most of the bombs due to the explosion.

Trivia
Interestingly, the bombs look like wingless Bubble Bats.
