Editing Hard Block

The first Hard Blocks appeared in ''[[Super Mario Bros.]]'' They are referred to as '''stairblocks''' in the companion book ''[[How to win at Super Mario Bros.]]'',<ref>{{cite|author=Sase, Shinji, [[Howard Phillips]], and Lynn Griffes, editors|title=''[[How to win at Super Mario Bros.]]''|format=U.S. Edition|date=1987|location=Redmond|publisher=Tokuma Shoten, [[Nintendo|Nintendo of America]]|isbn=4-19-720003-XC|page=7}}</ref> and their most notable use is to create stairs at the end of many levels leading to the top of the [[Goal Pole|flagpole]], which itself has a Hard Block as its base. In some levels, they are used to create much more gently-sloped stairs as a minor obstacle. Stairblocks reappear in ''[[Super Mario Bros.: The Lost Levels]]'' with an identical appearance and purpose. They are also incorporated into ''[[Super Mario Bros. Special]]''.

Hard Blocks also appear in ''[[Super Mario Bros. 3]]'', where they are known as '''Wood Blocks'''.<ref>{{cite|author=Peterson, Erik|date=2003|title=''Super Mario Advance 4: Super Mario Bros. 3'' Player's Guide|page=31|publisher=Nintendo of America|language=en-us|isbn=1930206-37-2}}</ref> Some Wood Blocks are bouncy; these blocks bounce Mario or Luigi away if he runs against their sides, and they are sometimes found near [[pit]]s as an obstacle. Some of these blocks also hold items, releasing them only if they are bumped into or hit with a [[shell]] or tail whip (from [[Raccoon Mario]] or [[Tanooki Mario]]). [[Chain Chomp]]s are usually found attached to Wood Blocks. Larger inert Wood Blocks appear in the fourth world, [[Giant Land]].

Hard Blocks, now called '''Gray Blocks'''<ref>{{cite|title=Nintendo ''[[Mario Mania]]'' Player's Guide|date=August 1991|page=71, 89, 108, 153|language=en-us|publisher=Nintendo of America}}</ref> (alternatively '''gray Blocks'''<ref>{{cite|title=Nintendo ''Mario Mania'' Player's Guide|page=57|date=August 1991|language=en-us|publisher=Nintendo of America}}</ref> or '''Grey Blocks'''<ref>{{cite|title=Nintendo ''Mario Mania'' Player's Guide|page=73|date=August 1991|language=en-us|publisher=Nintendo of America}}</ref>), appear once again in ''[[Super Mario World]]'' with a different redesign, this time resembling blocks of stone. They reprise their purpose from previous games.

Hard Blocks (localized as '''orange blocks''')<ref name>{{cite|author=Averill, Alan, and Jennifer Villarreal|title=''Super Mario Sunshine'' Player's Guide|page=73|location=Redmond|publisher=Nintendo of America|language=en-us|date=2002|isbn=1-930206-23-2}}</ref> primarily appear in secret courses as platforms and barriers. Many are of atypical shapes (i.e., rectangular or triangular prisms) depending on their purpose. Some shift back and forth. Thin variants that function like [[trampoline]]s appear in [[The Secret of the Dirty Lake]] and [[The Beach Cannon's Secret]].
