Walking Block

Walking Blocks are stone creatures resembling Thwimps found in Donkey Kong for the Game Boy. They first appear in Stage 3-1 on the Ship. Walking Blocks slowly walk horizontally, including across spikes. Mario can jump onto them to cross larger areas of spikes. Walking Blocks do not hurt Mario in any way, although they do sometimes block his path.
