Strollin' Stus are squat, pudgy creatures, somewhat similar to Goombas, native to Isle Delfino found in the game Super Mario Sunshine. They have a bulbous nose, high-tucked spotted trousers, and a waddling gait. If sprayed with water, they flip over- the player can then walk into them to kick them away. They can be defeated either by a stomp to the head, or by kicking them into a wall- in the latter case, it will leave a splatter of Goop "blood" where they impacted, which disappears after a few seconds. Strollin' Stus are particularly hostile, and will charge if approached. They are the most common variant of Stus encountered in the game.
Stus are known to stack themselves up onto each other on top of a Giant Stu in a form known as a Stackin' Stu. If Mario knocks all the Strollin' Stus off the Giant Stu and jumps on the Giant Stu, he will get a Blue Coin and all the Strollin' Stus vanish.
A larger variety known as a Swipin' Stu can also steal Mario's Cap, causing him to become damaged from the rays of the sun. A simple stomp on the head will defeat them. These Stus can be found at the Delfino Airstrip, Bianco Hills, Pinna Park and some secret areas. They can easily be defeated in large groups by using a quick squirt from F.L.U.D.D.
