Orange cube

Orange cubes are beakable objects in Super Smash Bros Brawls adventure mode. Unlike green cubes, orange cubes don't come back once you break them.

Trivia

 * Orange cubes are not easy to find.

Levels with Orange cubes
That list is far too long, so I'll list the levels that don't have them.

Midair Stadium

The Ruined Hall

Battleship Halberd Bridge

Now, imagine if I did list the levels that had them.
