Throughout this level, Bullet Bills will shoot across the screen from the right side of the screen, at random locations.
Jump onto the tree, then jump up to the next tree. The tree above that has a red Koopa Troopa going back and forth, so go up there carefully to get the three coins.
Next, fall down to the right to get the coin on the low tree. Then jump up onto the tree on the right, watch out for the Goombas that come from the tree above that, then make a running jump to get the two coins in the air.
Jump on the tree where the Goombas fell from, then jump down to the right to get the two coins and land on the tree below.
To the right, there is a ?-mark block that contains a Mushroom or Fire Flower. After you get it, jump onto the platform that goes up and down, and jump onto the tree at the top to get four coins.
There are a couple of trees to the right, followed by a red Paratroopa. Bounce on the Paratroopa or jump over it to reach the tree to the right, which has a Goomba on it at first.
To the right of that, there is a moving platform. Jump on it and get the two coins above it, then jump on the moving platform on the right and get the four coins in the air above it.
Jump from there to the tree on the right. The tree after that has a red Koopa Troopa going back and forth, so jump carefully onto that tree.
To the right of that, a red Paratroopa is going up and down. Stomp on it or avoid it and fall down below to get the three coins on the low tree.
Jump up onto the tree on the right, then jump across to get the two coins there. Those are the last coins in the level.
Jump onto the moving platform on the right, then jump up onto the stairs. Go to the top and make a running jump onto the goal pole, which will take you to World 5-4.
