Yoshi's Island 2

Go right and pick up the red shell on the ground.

Jump onto the higher ledge.

Throw the red shell at the line of Koopas ahead to clear them and get a 1-Up for clearing eight enemies in a row.

Run off the ledge and collect the mushroom from the newly created ! block.

Proceed to another two blocks; hit the second one to unleash Yoshi for the first time.

After Yoshi's dialogue, jump on him.

Go right, eat the red Koopa, and collect the first Dragon Coin above.

Kill the next Koopa and collect the second Dragon Coin above.

Go up the steps, watch out for the charging Chuck at the top, and jump off the ledge to collect another Yoshi Coin.

Bowl through the checkpoint (an auto-save point you restart from on death).

Go over the yellow pipes and hit the three blocks.

One of these blocks contains another Yoshi egg; if you have Yoshi, a 1-Up green mushroom pops out instead.

In the next ledges area, wait above the dirt where moles appear and stand above them so they hit underneath you for a quick kill when they jump out.

To the right of the ledges area, hit the second of two blocks to make a vine appear.

Dismount Yoshi and climb the vine to reach a set of clouds and Dragon Coin No. 4.

Go back down and ride Yoshi again.

Go right and grab the fifth Dragon Coin above.

Pop the block to grab a mushroom.

Proceed to a blue pipe and travel down.

In the cave area, to hit the flying blocks far up, either grab the blue blocks in the middle and throw them up, or if you still have Yoshi, jump and dismount to get enough height.

These blocks contain mostly coins, and one contains a 1-Up green mushroom.

Exit the cave through the pipe to the right.

When you appear from the grey pipe, go right to the yellow blocks surrounding the P-Switch.

Hit the block underneath the P-Switch to make it drop down.

Jump on the P-Switch to make the coins turn into blocks.

Jump onto these new blocks and exit the level.
