Coral is a minor obstacle found in Super Mario Bros., where it is found in World 2-2 and World 7-2. It cannot harm the player, though it acts as a barrier that Mario must swim around. Coral is pink and acts similarly to Hard Blocks. The player can stand on the coral, but the enemies can swim through it. In World 9 of Super Mario Bros.: The Lost Levels, coral is placed horizontally and serves as a platform. Coral also appears in Super Mario Bros. 3 in a few levels, but it serves the same purpose as it did in Super Mario Bros. In Super Mario Bros. 3, it resembles a large stack of rings, though large versions of Super Mario Bros.-like coral can be found in World 4-4. After making common appearances as a simple background element in many games, coral as an obstacle returns in Paper Mario: The Thousand-Year Door, where it is found in an underwater level and can be destroyed by Bowser's fire breath.
