Snowman

Snowmen are sculptures made out of snow that have appeared as either obstacles or living creatures throughout the Mario franchise.

Super Mario 64 / Super Mario 64 DS
The world Snowman's Land in Super Mario 64 and its remake takes place around a very large snowman.

Super Mario Galaxy
Snowmen appear in Super Mario Galaxy in snow-themed areas, such as the backside of the icy planet in the Freezeflame Galaxy and in the Snow Cap Galaxy. These Snowmen have Star Bit features and orange hats, and are made up of two segments. It takes two fireballs from Fire Mario or Luigi to destroy them, with each destroying one segment. If the Star Bits haven't been already collected via the cursor, they will scatter everywhere when it is destroyed.

Super Mario Galaxy 2
In Super Mario Galaxy 2, numerous Snowman sculptures of Goombas and Bowser appear in the Freezy Flake Galaxy. Also, a snowman-like boss, Sorbetti, appears as the boss of the galaxy.

Super Mario Maker 2
Snowmen also appear in Super Mario Maker 2, where ones resembling Mario and Peach can be seen in the background of snow-themed levels. As of the 3.0 update for the game, they also appear in Super Worlds. When a course icon is tapped on and held, some options appear which the player can use to customize how that course icon looks (give it a pool of water, replace it with a Galoomba, etc.). If the player selects the option to put snow around it, a snowman resembling Mario also appears within the snow. When that course is cleared, the snowman's hat and scarf turn green, causing it to resemble Luigi instead.

Mario Kart series
Snowmen appear as obstacles in the Mario Kart 64 course Frappe Snowland (which reappears in Mario Kart DS and Mario Kart Tour), the Mario Kart: Super Circuit course Snow Land, the Mario Kart: Double Dash!! course Sherbet Land, the Mario Kart DS course DK Pass (which reappears in Mario Kart 7 and Mario Kart Tour) and the reverse variant of the Mario Kart Tour course Vancouver Velocity. They are also present in the Mario Kart 7 battle course, Sherbet Rink.

In most of their appearances, when the player collides with a snowman, the player will drop any items they have, and they will be knocked backwards a fair way. In DK Pass, they can potentially knock the player off the edge. However, in Mario Kart Tour, where they are referred to as snowpeople, they simply cause racers to slow down without crashing them. While snowmen are part of the background in Sherbet Land from Mario Kart: Double Dash!!, Mario Kart 8 and Mario Kart 8 Deluxe has made them obstacles that can be bumped into, though still in the off-road segments. Snowmen have scarves around their necks. In Mario Kart DS, they appear in mission 5-2 where the player has to avoid them while collecting coins, otherwise they fail the mission.

Paper Mario
In Paper Mario, Snowmen play an important role in the area of Shiver Snowfield where they act as the guards of the secret door to Shiver Mountain. The only way to get past them is to bring them a scarf for the scarf-less snowman and a bucket for the hat-less snowman. After Mario does this, the snowmen thank Mario and open the door to Shiver Mountain for him. In addition, Mario will be able to receive items when he sleeps in the Toad House in Shiver City after he helps out these snowmen. Goombario's tattle says, "It's a snowman. There're so many of snowmen! [sic] They don't melt because it's cold here. The way they're standing...they remind me of gatekeepers."

Paper Mario: The Thousand-Year Door
A Bob-omb snowman, built by a Bob-omb named Gob, makes a very minor appearance in Fahr Outpost in Paper Mario: The Thousand-Year Door.

Donkey Kong Jungle Beat
In Donkey Kong Jungle Beat, groups of three Snow Men decorated with bananas, a scarf, and blue hat appear in the cold climate levels, such as Ice Warren and Aurora Glacier. Upon noticing Donkey Kong, the Snow Men shift their heads into his direction and attempt to block his path. Snow Men often remain in one position and stare at Donkey Kong. Donkey Kong can easily defeat a Snow Man by sliding into it or by using his Sound Wave Attack. Upon defeating one, Donkey Kong is rewarded with a banana.

Super Princess Peach
In Super Princess Peach, Snowmen appear in some of the levels of Gleam Glacier. They serve as merely harmless obstacles, and Peach can destroy them by hitting them with Perry or destroying them with the fire from her Fury Vibe. After being destroyed, they usually release coins.

Super Mario-Kun
A snowman appears in volume 36 of Super Mario-Kun. In the beginning of the chapter, Baby Luigi finds a broken snowman, and rebuilds it. It then saves the Mario Bros. by stopping a Shroob bomb from exploding, but the captain shoots a lazer at the snowman, leaving Baby Luigi crying. After Baby Luigi freeze the Shroobs, Baby Mario rebuilds him, ending the chapter.

Mario & Sonic at the Olympic Winter Games
In the Nintendo DS version of Mario & Sonic at the Olympic Winter Games, Snowmen appear during the adventure mode. If Mario and Sonic the Hedgehog interact with them, one of the Snowman's hats will reveal briefs about the characters, details about the location of each snow spirit, and occasionally hearts. Snowmen also serve as obstacles in the Dream Event Blazing Bobsleigh.

Mario & Sonic at the Sochi 2014 Olympic Winter Games
Snowmen appear as obstacles in Groove Pipe Snowboard in Mario & Sonic at the Sochi 2014 Olympic Winter Games, where they slowly move around the course and cause the player to be slowed down when hit, though are destroyed upon impact. In this game, the snowmen have hats and green cloaks featuring a star pattern and the Sochi 2014 logo.
