Usually larger variants of [[Koopa Shell]]s that come from [[stomp]]ed [[Big Koopa Troopa]]s, big shells typically destroy large swathes of terrain when launched. Unlike normal-sized shells, big shells do not ricochet off of struck blocks, instead plowing through them, making them useful for solving certain puzzles or clearing obstructions. In some titles, the shells are too large to be picked up on their own, only [[kick]]ed.

Giant Shells are introduced in ''[[Super Mario Bros. 3]]'', on the backs of [[Big Koopa Troopa|Green Gargantua Koopa Troopa]]s and [[Big Koopa Troopa|Red Giant Koopa Troopa]]s in [[Giant Land]]. Stomping on these Koopas makes them retreat into their shells, making them available for use. Unlike subsequent titles, [[Mario]] (or [[Luigi]]) can carry Giant Shells on their own volition regardless of their form. Though they can be green and red, Giant Shells function the same way regardless of their color, as with the normal-sized Koopa Shells in ''Super Mario Bros. 3.'' They are the only shells capable of breaking the [[Mega ? Block]]s also found in Giant Land.

In ''[[Super Mario Advance 4: Super Mario Bros. 3]]'', Giant Shells also appear in the promotional [[e-Reader]] course [[Treacherous Halls]], where stomping on the Green Gargantua Koopa Troopa that walks along the [[Spike Trap|spike]]s sends its shell flying into [[Mega Goomba|Grand Goomba]]s.

While Big Koopa Troopas are absent from ''[[Super Mario Bros. Wonder]]'', big shells appear as part of [[Hefty Swirlypod]]s, functioning as they did in the ''Super Mario Maker'' titles. Stomping Hefty Swirlypods ejects them from the shells, which can then be kicked to break terrain and [[Hard Block|hard block]]s. Player characters can only pick up big shells if they are in their [[Elephant Mario|Elephant form]]s, and big shells themselves mostly appear in courses that also feature the [[Elephant Fruit]] power-up. Characters in their Elephant form can handle big shells like they would smaller ones, being able to drop them, [[Shell Toss|toss]] them, and kick them upwards.

Big shells first appear in [[Swamp Pipe Crawl]], where they can be used to clear hard blocks, some of which block access to a [[Warp Pipe]] leading to a background area holding a [[10-flower coin]]. Big shells subsequently appear in [[The Anglefish Trial: Ready, Aim, Fly!]] in a similar capacity, where one must be used to unobstruct a pipe and tossed upwards to collect a 10-flower coin.
