Bomps (also known as Moving Bars, Pushy Walls, or Sliding Stones) are a species of Thwomp that first appeared in Super Mario 64. They are living, pushing, protruding stones that act as obstacles in many games. Their name is a portmanteau of "bump" and "Thwomp."
Super Mario series
Super Mario 64 / Super Mario 64 DS
Moving Bars made their first appearance in Super Mario 64 and its Nintendo DS remake, Super Mario 64 DS. They appear in the course Whomp's Fortress. At the beginning of the course, they go through a pattern of pushing, trying to shove Mario off a cliff, and subsequently making him fall down the course's pit. The beginning and end Moving Bar in Whomp's Fortress are thinner than the center Moving Bar. Their eyes have a blue outline with blue pupils, and a thick black outline along the tops. An eyeless, mechanical version of Moving Bar also appears in Tick Tock Clock. Like the other pieces of the clock, they are affected by how Mario enters the clock and are used as platforms as well as obstacles.
In Super Mario 64 DS, no Moving Bars have eyes, and their moving patterns have been altered to appear more in unison. The Moving Bars in Whomp's Fortress can also be destroyed if hit by a character powered up by a Mushroom.
Super Mario Galaxy
Super Mario Galaxy 2
In Super Mario Galaxy 2, they appear with the same role and appearance as in Super Mario Galaxy. They appear in the Fluffy Bluff Galaxy and the Throwback Galaxy, the latter which is a remake of Whomp's Fortress. In the Fluffy Bluff Galaxy, Bomps can assist the player in climbing the slope where they are located, but in the Throwback Galaxy, their purpose is more like that of an obstacle.
Paper Mario: Sticker Star
Bomps make an appearance in Paper Mario: Sticker Star in the Chomp Ruins, retaining their appearance in Super Mario Galaxy. In the game, they are made of cardboard instead of stone. They come out from waterfalls and double doors. An upside-down Bomp appears as a Scrap, and it must be flipped over using Paperization so that Mario can reach the Ruin Floor Scrap.
