Mega Grrrol

Dai Gorō are large Grrrols that first appear in New Super Mario Bros. U. They are similar to Spiny Tromps from the Paper Mario series. They share a similar appearance to Grrrols down to the missing tooth, though with twenty spikes and a much wider smile.

New Super Mario Bros. U / New Super Luigi U / New Super Mario Bros. U Deluxe
Dai Gorō are found alongside their smaller counterparts in the first Rock-Candy Mines tower, Grinding-Stone Tower, in New Super Mario Bros. U, and its equivalent level in New Super Luigi U, Smashing-Stone Tower. One is also found at the end of Underground Grrrols, and a few more are found in Stone-Snake Tower. In all four levels, Grrrols are the primary obstacles. Dai Gorō generally appear in confined areas and roll back and forth as obstacles, rather than coming from generators like normal Grrrols. Like normal Grrrols, they can also smash through Brick Blocks.

Super Mario Party
In Super Mario Party, Dai Gorō can appear as obstacles in the Follow the Money minigame.
