World 4-3 (Super Mario Bros.)

World 4-3 is the third level of World 4 in Super Mario Bros. and the fifteenth level overall in said game. Unlike most ground levels, which have a green or gray palette for objects, this level has an orange and red one for the tall Super Mushrooms, which also affects the flagpole.

Layout
This level takes place on tall Super Mushrooms, some of which are lined with coins and/or Koopa Troopas and are separated by scale lifts or Koopa Paratroopas. Over the third tallest Super Mushroom is a ? Block containing a power-up. After the first scale are two vertically moving lifts, and afterward are a group of three scales before a final lift that can be used to reach the top of the flagpole.

Super Mario Bros. Deluxe challenges
In Super Mario Bros. Deluxe, the player can collect five Red Coins, find a hidden Yoshi Egg, and get a medal based on their score. The Yoshi Egg is found in a Hidden Block to the left of the second to last Super Mushroom (directly above the cloud), and the score to beat is 24000. The Red Coin locations are:
 * Underneath the second tallest Super Mushroom
 * Underneath the first scale platform
 * On the bottom Super Mushroom after the second vertically moving lift
 * Underneath the final scale platform
