Vegetables (also known as Veggies and Sprouts) are items that can pulled out of the ground andf thrown at enemies to damage or defeat them. They are first introduced in Yume Kōjō: Doki Doki Panic (a Turnip only) and the Mario game, Super Mario Bros. 2.
Super Mario series
Super Mario Bros. 2
Vegetables are first found in Subcon in the game Super Mario Bros. 2. They can be plucked with the B button and thrown at enemies. There are two kinds, unripe and ripe. The ripe ones are much larger than the unripe but they're still just as effective when throwing. Almost all the red grass in the game is a vegetable when plucked. Some of the ideas for what kinds of vegetables they are is turnips, onions, beets, radishes, and other root vegetables.
These are the only effective weapon against the evil Wart in the last level. The pale vegetable in the bottom right side of the picture to the left is only seen when thrown out of Wart's Dream Machine.
BS Super Mario USA
Vegetables returned in the game BS Super Mario USA. They are used in the same manner in the predecessor. The game introduces giant vegetables that can't be picked up. Instead, these giant plants only appear as spells cast by a character who appears on the screen as a card.
Super Mario Advance
Vegetables return in Super Mario Advance, working the same way they did originally. This version of the game, however features pickable giant vegetables, which take longer to pull out. They work the same as their normal-sized counterparts, but can hit more enemies, due to their bigger size.
Super Mario Advance 4: Super Mario Bros. 3
Using e-Cards, vegetables can be brought into Super Mario Advance 4: Super Mario Bros. 3 thanks to the Blue Green Switch. They can be used in the same manner. The game also features pickable giant vegetables, from Super Mario Advance.
The Super Mario Bros. Super Show!
Vegetables appeared in some episodes of The Super Mario Bros. Super Show!. Mario and Luigi use them in various episodes to defeat their enemies, the Koopa Pack and King Koopa like in Super Mario Bros. 2. The vegetable-throwing sound from Super Mario Bros. 2 is also commonly used in the show even for things such as the firing of a Bullet Bill and the throwing of a fireball.
Mario vs. Wario
Vegetables were given a minor appearance in one of the Mario vs. Wario comics. The first page of this comic showed Mario recalling "playing in the garden" with Wario when the two were friends; during this scene, several vegetables are present and Wario even picks one up Super Mario Bros. 2-style. Wario, too, remembers this garden scene on the next page, although his memory is a bit less fair: He recalls Mario asking for help in the garden and taking a row of turnips as his own, leaving Wario to tackle the Piranha Plants on his own.
Super Smash Bros. series
In the Super Smash Bros. series, Princess Peach can also throw these items as her down & B attack, which itself is called "Vegetable". Almost every one she plucks has a different expression, which pertains to the amount of damage it will inflict. The damage of the Vegetables range from 7% damage to around 35%. Peach can also pluck up Beam Swords, Mr. Saturns, and even Bob-ombs. In Super Smash Bros. Melee, there is a Vegetable trophy.
Another type of vegetables are food items that are only found in the Brawl stage Summit. When they are eaten, they make a special, different sound effect from the other foods.
In Super Smash Bros. for Nintendo 3DS / Wii U, the Vegetables can be customized to one of the two custom variants, after they are unlocked. One is the Light Veggie, a slow-flying vegetable, but it can only be used twice in a row. The other one is the Heavy Veggie, which has shorted range, but it deals more damage.
Mario & Luigi: Bowser's Inside Story
In the boss battle with Wiggler in Mario & Luigi: Bowser's Inside Story, the Wiggler may water the ground and some sprouts will grow. Two of the three possible things he pulls out are ripe and unripe turnips.
Captain Toad: Treasure Tracker
Turnips make a reappearance in Captain Toad: Treasure Tracker, after an absence of five years. This game also marks the debut of the turnips in a true 3D environment. However, their appearance has changed. Instead of red grass, the turnips are pulled from green sprouts attached to metal yellow plates that turn brown after the turnip is pulled out, similar to ? Blocks. Captain Toad relies on the vegetables as his main source of attack and can pluck turnips from the ground from vegetable sprouts that appear throughout the levels of the game. Much like in Super Mario Bros. 2, the vegetables can be thrown at enemies to defeat them. Both Captain Toad and Toadette can further use the turnips at obstacles such as POW blocks in order to discover new pathways.
Captain Toad will also use giant turnips in Wingo's boss fights. Unlike regular turnips, the giant turnips sprouts must be pulled upon several times in order to pluck them out of the ground as a result of their massive size.
