Big Pokey

Big Pokeys are larger varieties of Pokeys first appearing in Super Mario Galaxy. Their body is twice as large compared to a normal Pokey.

Super Mario Galaxy
In Super Mario Galaxy, only two Big Pokeys appear in the entire game. One appears on one of the tropic planets in Good Egg Galaxy, and the other appears on one of another pair of planets in 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.

Mario Kart Wii
A single Big Pokey appears in Mario Kart Wii. It 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. Bob-ombs were used to attack it, and as it got damaged, body segments would move around.

Mario & Luigi: Paper Jam
In Mario & Luigi: Paper Jam, Big Pokey appears as a boss in Doop Doop Desert alongside Paper Tower Power Pokey.
