Face Blocks are a type of block featured in New Super Mario Bros. and later returning in Super Mario 3D Land.
Description[]
A Face Block is a yellowish block with a face on it, generally one with a neutral expression. At first, there is only one Face Block, but each time Mario or Luigi hits it, another Face Block pops out from below it. Up to four Face Blocks can be out at a time. Face Blocks allow Mario or Luigi to either reach higher platforms or enter pipes facing horizontally. After a while the Face Blocks collapse back into one Face Block.
In Super Mario 3D Land, Face Blocks instead spawn from ! Blocks temporarily. Besides this, Face Blocks are otherwise the same as in New Super Mario Bros..
