Hidden Item Container
From the Super Mario Wiki
(Redirected from Roulette (object))
Hidden Item Containers, also known as Roulettes, are objects the player can pick up in Super Mario Advance. They can be randomly found under Mushroom Blocks or behind destructible walls. Three items scroll within it: a bomb, a heart, and a Starman. When the Hidden Item Container is dropped, it breaks and releases whatever item is shown.
