Super Mario series
Super Mario Bros. 2
In Super Mario Bros. 2, they are the main modes of transportation of Subcon; if a character goes down a jar, they will appear in a small room sometimes containing a key being protected by a Phanto. In some levels, certain jars within Subspace contain a Subspace Warp that allows the player to warp to a further world, acting as the Warp Zones of Super Mario Bros. 2. Magical Potions will not work inside jars though. Cobrats sometimes lurk in the opening of some jars. Certain jars generate endless streams of enemies like Bob-Ombs or red Shyguys unless their entrances are blocked. In Super Mario Advance, some jars also contain Sparks and Spark Chasers, as well as (sometimes Shyguy-ridden) Ferris wheel platforms and one contains a bouncing blade; jars were also added to levels in that version, and certain closed-off jars in previous versions were opened.

Super Smash Bros. series
Jars made a small appearance in the background of the Super Smash Bros. Melee stage Mushroom Kingdom II, which also took place in Subcon. As the stage returns in Super Smash Bros. Ultimate, the jars there also return.
Mario Pinball Land
Four jars appear on the first pyramid interior board of the Shifting Sands Stage in Mario Pinball Land. In this appearance, they have earthy colors and diamond shapes on their pattern. They cannot be interacted with as their corners are elevated, but Snakes come out of them if the top middle tile is activated.
