Bomps are Thwomp relatives 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[edit]

Super Mario 64 / Super Mario 64 DS[edit]

Bomps made their first appearance in Super Mario 64 and its Nintendo DS remake, Super Mario 64 DS; herein, they are known as Moving Bars.[1] The first type, also known as Pushy Walls,[2] appears 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 Bars are thinner and faster than the center one. Their eyes have blue irises with black pupils, and a thick black outline along the tops. An eyeless, mechanical type of Moving Bar appears in Tick Tock Clock. They have a spring-like recoil unlike the previous ones. 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. Objects similar to Moving Bars also appear as platforms in Bowser in the Dark World and Bowser in the Sky, although they again have slightly different sliding behavior.

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[edit]

Bomps reappear in Super Mario Galaxy, where they now more closely resemble Thwomps. They appear in the Buoy Base Galaxy and the Freezeflame Galaxy. Similar objects also appear as part of the Cyclone Stone.

Super Mario Galaxy 2[edit]

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. Like before, similar objects appear in Stone Cyclone Galaxy.

Paper Mario: Sticker Star[edit]

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.

Mario Party 10[edit]

Bomps made their Mario Party series debut in Mario Party 10 in the minigame Cliffside Crisis, where they serve as both obstacles and platforms for the players.

  • In Super Mario Galaxy, Bomps are two-sided, having a face on each end of their model.[6] Most of the time, the second face is inside the wall and can't be seen from outside, but sometimes the second face will come out of the other side of the wall as if it were another Bomp. This can be seen with a few pairs near the peak of the ice mountain in the Freezeflame Galaxy.
  • In Dreamy Mount Pajamaja in Mario & Luigi: Dream Team, there are stone hands that act similarly to Bomps. The Push-Blocks of Super Mario Odyssey also act like them.
