Mystery Crate

A Mystery Crate, also called a blue Question Mark Box  and erroneously called a ? Block by an English-language Message Block, is an object found in Yoshi's Story. It is one of the most common objects in Yoshi's Story. To open a Mystery Crate, a Yoshi has to ground-pound on the top of it. Mystery Crates usually contain melons. These items can also be pushed. There is also an enemy called an Air Bag that is disguised as a ordinary Mystery Crate. However, the disguised enemies cannot be pushed.
