Wooden Block

A Wooden Block is a type of block that is found in Super Mario Bros. 3 that cannot be destroyed. Some Wooden Blocks may contain an item, but they will not turn into a Used Block after being hit. Wooden Blocks will only ever yield items if they are hit from the side, and not from underneath. Mario or Luigi need only to press against the side of a Wooden Block containing an item in order to reveal it, as opposed to having to use a Shell or a Raccoon tail like with other types of block. In Super Mario Bros. 3, Chain Chomps are attatched to these.

These blocks were going to return in Super Mario World, but were cut from the final version. There are two Rotating Blocks that act like the ones that yield items, and one only yields Cape Feathers while the other one does nothing (presumably, this one is what the Feather block would become once it released its Feather).

Wooden Blocks return in the Nintendo 3DS game Super Mario 3D Land, where they're bigger and more yellow than the ones in Super Mario Bros. 3.

Wooden Blocks will appear in the upcoming game, New Super Mario Bros. 2, looking similar to their first appearance version. They are used as solid and stationary platforms.
