Big Pokey

Big Pokeys, also known as Giant Pokeys or Mega Pokeys, are larger varieties of Pokeys first appearing in Mario Kart: Double Dash!! and having more appearance in Super Mario Galaxy and Super Mario Galaxy 2.

Mario Kart: Double Dash!!
In Mario Kart: Double Dash!!, five Big Pokeys appear as obstacles alongside seven normal-sized Pokeys in Dry Dry Desert. They are positioned in place and put their head on the ground at regular intervals, forming a hoop shape that the racer can drive through. They do not appear in the Mario Kart 8 rendition of the course.

Mario Kart Wii
In Mario Kart Wii, a single Big Pokey appeared in Thwomp Desert exclusively in the tournaments of October 2008 and September 2009. The players had to battle the Pokey, which was located at the center of the course, using Bob-ombs to attack it; running into any part of the Pokey would stun players for several seconds, and as it got damaged, body segments would move around.

Super Mario Galaxy
In Super Mario Galaxy, only two Big Pokeys (known as Pokeynuts or simply Pokeys) appear in the entire game. One appears on one of the tropic planets in the Good Egg Galaxy, and the other appears on one of another pair of planets in the Dusty Dune Galaxy. To defeat one, Mario or Luigi must spin a coconut into one to knock all of its segments down, and jump on its head to finish it off. Doing so will make a Launch Star appear.

New Super Mario Bros. U
In New Super Mario Bros. U, Big Pokeys appear in Morton Koopa Jr.'s boss fight. Morton uses his hammer to knock the invulnerable Pokey segments at the player.

They reappear in New Super Luigi U with the same role.

Yoshi's New Island
In Yoshi's New Island, a regular Pokey named Punkey is transformed by Kamek into a giant-sized Pokey as a boss of World 5.

Mario & Luigi: Paper Jam
In Mario & Luigi: Paper Jam, Big Pokey appears as a boss in Doop Doop Dunes Grotto alongside Tower Power Pokey. In battle, it attacks by lying sideways and rolling forwards and backwards, an attack which can potentially damage Mario, Luigi, and Paper Mario based on how many segments the Big Pokey currently has. Destroying the Big Pokey's segments will deplete its range, although it can grow these segments back if Paper Tower Power Pokey has more. The only way to defeat Big Pokey is by attacking its head.

Big Pokey has a substantial amount of health and attack power, and will become enraged when Paper Tower Power Pokey is defeated (and vice versa).

Paper Mario: The Origami King
At least one Big Pokey, known as Mega Paper Macho Pokey, makes an appearance in Paper Mario: The Origami King, marking the enemy's first appearance in a Paper Mario game. He is a Paper Macho variant, and is fought in the Scorching Sandpaper Desert.
