Big Wigglers (also known as Giant Wigglers) are a sub-species of Wiggler that first appeared in New Super Mario Bros.. They are five times the size of a normal Wiggler, but they are not bigger than Super Mario Sunshine's Wiggler, and live beneath the ground near acid pits.
Super Mario series
New Super Mario Bros.
In New Super Mario Bros., a Big Wiggler appeared in World 7-3. Mario or Luigi has to ride on the Big Wiggler through the entire level while avoiding enemies and obstacles. This Big Wiggler is even larger than average Big Wigglers.
New Super Mario Bros. Wii
In New Super Mario Bros. Wii, despite being enemies, Big Wigglers can help Mario get items normally out of his reach. For this, the players must jump over a Big Wiggler and press the or button to do a high jump, as if they were using a Spring.
Big Wigglers can hurt Mario by running into him while on their preset paths. They can also defeat Swoopers, along with most other enemies upon making direct contact. Also, they don't get angry if Mario jumps atop them.
It should also be noted that the Big Wiggler is one of the very few enemies that cannot be defeated by any means and are invincible. They can only be defeated by reaching the flag at the end of the level just like King Bills.
Super Mario Galaxy 2
Big Wigglers reappear in Super Mario Galaxy 2 in the Supermassive Galaxy. They appear on the Stone Tube Planet, and Mario must avoid touching them to reach the Power Star. One that appears in an angry state circles the tube towards the end. They can't be defeated, but the Co-Star Luma is able to stop them from moving and hurting Mario.
New Super Mario Bros. U
Super Mario Maker
Big Wigglers are set to reappear in Super Mario Maker. Big Wigglers appear in all styles. Unlike in New Super Mario Bros. U, they appear slightly smaller and have the same behaviour as regular Wigglers as they can become angry and can be defeated.
Mario Kart series
Maple Treeway makes a reappearance in Mario Kart 7, and so do the Big Wigglers.
