Super Mario Bros. 2
If Mario and his friends first pull up four large vegetables in Super Mario Bros. 2, pulling up what would be a fifth one will instead reveal a Stop Watch. It will appear for a second and then freeze everything in the level for a few seconds. This gives a window of opportunity for Mario and his friends to avoid or defeat enemies and collect small hearts. However, touching the frozen enemies still hurts the player.
Paper Mario series
The Stop Watch later appears as an item in Paper Mario. When Mario or his partners use it, it will immobilize enemies for a few turns (assuming it is successful). It can be bought at most stores and is a fairly common item.
Paper Mario: The Thousand-Year Door
It reappears in Paper Mario: The Thousand-Year Door as the Stopwatch. Here, it is a somewhat rare item, for it can only be purchased in Twilight Town or Fahr Outpost. The item will immobilize enemies, just as in the game's predecessor. However, enemies can also use the item against Mario or his partners. Several warped clocks appearing in various colors will appear on-screen after using the item. After about four seconds, the item takes effect and immobilizes its target.

Donkey Kong Land III
Six related items known as Watches or Clocks appear in Donkey Kong Land III. Watches, however, cannot be used during gameplay. They are obtained by completing the Memory minigame in each world, where Bear gives them to the player. They act primarily as collectibles which count toward a final game score of 100%, but also act to unlock various time trial challenges after King K. Rool is defeated for the second and final time. These time trials are merely select levels from the game which are timed, unlike in regular gameplay. Finishing six of the twelve total challenges, on top of collecting all major items in the regular levels, will lead to a perfect game score.
Mario & Luigi: Dream Team
Nintendo Comics System
In the Nintendo Comics System story Cloud Nine, it appears as an animate object who acts as the Mushroom King's alarm clock, dodging the grumpy King's attempts to swat him and fearfully running to Princess Toadstool for safety.
