Flower 4 (26)

Go through the bumpers and jump straight up to attract a red coin (15) towards you.

Eat the leaves off the flower enemy, then continue all the way right to the end.

Shoot an egg at the block to bring down a Stork Stop (a type of checkpoint (an auto-save point you restart from on death)).

Jump into the alcove where the Stork Stop was stuck to find another red coin (16).

Go left and jump to pull down the metal platform, which also pulls down two red coins (18).

Jump onto the platform so you can reach the ledges above.

If you want to use the Key, go right and unlock the door to play a flying mini-game for extra lives.

Otherwise, continue going up and to the left.

Head through the Middle Ring and jump to the upper ledges.

Hop to the right, pulling coins from the brush above.

Ignore the red switch for now; instead, continue right to the Stork Stop.

Switch to Baby Mario.

Go back and hit the red switch.

When the blocks appear, quickly run and jump to the right across them all, jumping to the ledge with the flower enemy at the end.

Eat the leaves off the flower enemy.

Jump to collect the fourth Flower behind it when it's safe.
