In this icy level you’ll be dealing with Snow Pokeys. You can’t just run up to them and often they are a bit too tall for you to simply jump upon. Use the Cat Power-Up to easily defeat them as you progress.
Collect the coins from the ? Blocks and cross the frozen water. Behind the first tree across the water is a Propeller Box , a useful item that doesn’t take away your Power-Up but instead is worn over top of it. Turn the corner and clear out the Bizzybuds to find Green Star #1 then loop around, continuing right.
Defeat the Snow Pokey and hit the ? Block to find a Super Leaf , another convenient Power-Up that grants the Tanooki Suit. Dash past the Goomba in the skate to reach the Checkpoint Flag .
Below in the ice rink are several Goombas, defeating them will give a skate you can use. Hit the Red Ring and claim the eight Red Coins to receive another Super Leaf . As you make your way up the ramps past the ice rink you’ll spot a few snowballs and a Rabbit. Grab a snowball and chase after the Rabbit, past the Biddybuds and give the snowball a good toss to stun the Rabbit and claim Green Star #2 .
At the next icy area you’ll have to contend with a few Snow Pokeys, but you can easily grab the Stamp from the narrow ledge on the left side. Before entering the green pipe, climb atop the tree and leap up using the Tanooki Suit to reach Green Star #3 , likewise if you have the Propeller Box still just fly up.
Take the green pipe to reach the Goal Pole.
