Big Whomp

Big Whomps are a larger sized sub-species Whomps. They are rather rare types of Whomps, having only 2 appearances. They are similar to Super Thwomps, as they can also break through Brick Blocks.

New Super Mario Bros.
Big Whomps made their first appearance in New Super Mario Bros. for the Nintendo DS. They are commonly found in castle levels and usually appear along side regular Whomps. They behave in the same way as normal Whomps, only Big Whomps are able to walk around freely instead of staying stationary in the background and falling on Mario or Luigi.

New Super Mario Bros. 2
Big Whomps reappear in New Super Mario Bros. 2. They once again appear in castle levels, though a few have appeared in a level in World Star. In this game, Big Whomps are again able to walk around, but they can also be seen in the background. Once a Big Whomp in the background falls, there can be Coins, Roulette Blocks or even a Red Ring behind them.
