Big Snakey in the anime intro for Megaman 8. Snake Man can be seen standing on its head
Big Snakey is a sub-boss from Snake Man's stage in Mega Man 3. Its body is the floor of the room its found in and is segmented, with the segments constantly shifting up and down. It's not necessary for the player to walk on the shifting part of the floor, but remaining on the flat ground can make the player an easier target for Big Snakey's fireballs. Big Snakey fires 2-4 blasts with each attack. Its head is the only part of it that can be shot since the rest of its body is part of the scenery.
