Super Mario 3D World: Star-8 -- Peepa's Fog Bog

The first part of this level is a graveyard covered in snow. There are Key Coins to collect. Some of them are not as obvious to reach. One on the left is above invisible clouds. One in the center requires hitting a POW Block. Go through the front right door to reach the Key Coin on the balcony. Dodge the many Peepas (ghosts) and Snow Pokeys. Towards the back are two headstones with glowing spots you should ground pound. The one on the right has a Starman. Get it and run to the back left corner to defeat the Peepas surrounding Captain Toad for the first Green Star. The headstone on the left has a Fire Flower. Once you collect the Key Coins, take the warp box to another area.

The warp box takes you to a raft on purple water. Grab the clock and the raft will drop you off at the midpoint. There are many Boos in the fog. Narrow wooden planks rise in and out of the fog. Memorize the path so you know which way is safe. On solid ground, you'll see two Mystery Boxes. The left one is fake. The right one leads you to a room where the second Green Star will disappear if you approach it. Quickly throw a snowball at it to get it from the stone tiles. The third Green Star is nearby, out over the fog. Grab a snowball from a Snow Pokey and throw it at the Green Star. Farther along, you'll find a boost pad. Make sure the path ahead is about to appear before you hit it and start running. Take the path to the right for the stamp. The warp box ahead takes you to the flagpole, where there are Peepas and invisible clouds.

The stamp is of Cat Rosalina.

Super Mario 3D World: 3-1 Snowball Park

There's lots of snow here. Even the Pokeys are made of snow. Use Fire Flowers to defeat them and parts of them will remain. Pick up the snowballs and throw them at enemies. Cross the first patch of ice and go behind the trees to find a Propeller Block. Keep it throughout the level. Walk forward and you'll see many Para-Biddybuds, the flying bugs. There's an alcove behind them with the first Green Star. Kill the enemies to clear the path to it. Go forward and go past the Snow Pokey. The item block has a Super Leaf, which gives you a Tanooki Suit. There's a Goomba in an ice skate. Kill the Goomba to get it. Skate around, which makes navigating on the ice easier, but you'll lose it if you run into something. Across the ice is the midpoint.

Slide down the slope to a large patch of ice with more Goombas in Kuribo's Ice Skate. There's a Red Coin Ring, with the Red Coins appearing in a circle around the ice-free zone in the center. Past the ice is a rabbit with the second Green Star. He can be a little tricky to catch, especially when he crosses the ice. Try using a shortcut to cut him off. It make take a while to catch him, so watch your time. Past the rabbit is a patch of ice with Snow Pokeys. On the narrow strip of ice is the stamp. On dry land, climb the tree near the wall, jump, and use the Propeller Block to reach a high alcove with the third Green Star. The pipe to the right will take you to the flag.

The stamp is of a Para-Biddybud.
