Stop Watch

Stop Watches (alternatively formatted Stopwatches  and also known as Time Stops ) are clock-like items that usually slow down or stop time when collected.

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
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.

Locations

 * In a hidden block in the first scene of the Ultra Boots area in Toad Town Tunnels.
 * On top of a Brick Block one screen south of the next-to-last part of the main road of Dry Dry Desert.
 * Behind a bush in the back of the shore where Whale resides.
 * In a hidden block before the stairs where Mario fights Monstar in Shiver Snowfield.
 * On sale at Boo's Shop (25 coins) and the Star Haven Shop (15 coins).
 * Dropped by Lakitus.

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.

Locations

 * In a rock on the Moon surface near where Mario lands.
 * Behind near the entrance in the first part of descending stairs in the Palace of Shadow.
 * On sale at Twilight Shop (30 coins) and Northwinds Mart (12 coins), and Charlieton (24 coins).
 * Dropped by ordinary Magikoopas, Moon Clefts, Bob-ombs, Bulky Bob-ombs, Bob-ulks, Wizzerds, Dark Wizzerds, Elite Wizzerds, X-Nauts, X-Naut PhDs, Elite X-Nauts, as well as the Dull Bones, Bob-ombs, and all the Fuzzies in Glitz Pit.

Super Paper Mario
The Stop Watch also appears as an uncommon item in Super Paper Mario, where it immobilizes all enemies.

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
The Stop Watch appears again in Mario & Luigi: Dream Team as a badge effect that occurs when mixing the Miracle Badge with the Gold Badge.

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.

Super Mario Bros. 2

 * Wii Virtual Console manual: "If you've pulled up enough vegetables, this item will temporarily freeze your enemies."

Trivia

 * An official 1989 Super Mario Bros. 2 character sheet that was given to third party companies getting the Mario license for products, included "Stop Watch" as a character. Despite the Stop Watch being merely an item in the original game, this character sheet gave the bottom of the watch part a base with eyes, mouth, legs and hands. This Stop Watch character is the same one later used briefly in the Nintendo Comics System story, Cloud Nine.
