This is Kirby's favorite snack. Eat this miracle fruit to regain all your strength!”
— Kirby 64: The Crystal Shards instruction manual
Maxim Tomatoes (called Bag of Magic Food and Magical Food in Kirby's Dream Land, sometimes referred to as simply Tomatoes) are recovery items. They are large, red tomatoes with a prominent black "M" in the center. In most games in the Kirby series they are the best healing item, since they recover all of a character's Health when eaten. As a result, tomatoes are Kirby's favorite food in the games.
The foe Poppy Bros. Jr. is sometimes seen riding on a Maxim Tomato instead of an apple. If Kirby attacks Poppy with anything other than Inhale (or an ability that uses the inhale technique, like Throw), he will destroy the Maxim Tomato. Inhaling will suck the Poppy Bros. Jr. off and allow Kirby to pick up the Maxim Tomato.
In Kirby's Epic Yarn, a Metamato (a tomato that resembles a Maxim Tomato made out of yarn) is the source of Yarn Kirby's shape shifting abilities. One is noticeably worn on the hat of the main villain Yin-Yarn, but is mistakenly eaten by Kirby (who thinks it's a Maxim Tomato) in the opening scene. This angers the yarn magician and prompts him to suck the pink hero into the sock around his neck, starting Kirby's adventures in Patch Land.
Maxim Tomato box
In Kirby's Return to Dream Land, some Maxim Tomatoes appear in Maxim Tomato boxes. They are red boxes with a Maxim Tomato on the side. They contain a Maxim Tomato and can be carried around until needed. After being thrown, the box will shake and then open up, allowing the Maxim Tomato to be eaten.
Reviving Tomatoes appear in Kirby: Triple Deluxe and Kirby: Planet Robobot. Always found encased in an Assist Star, they resemble gold tomatoes with a star on the center. They are given to Kirby by Bandana Waddle Dee when he loses to a boss three or more times in a row. In addition to healing Kirby's health when used, they will automatically revive him to full health if he has one in storage when he is KO'd.
In Kirby Mass Attack, a Maxim Tomato gives 100 points on the fruit meter. Since it takes 100 points to fill the meter, it is guaranteed that the player will get a new Kirby and/or a 10,000 point bonus when eating one. Also, in the Kirby Questsub-game, the first three Chapters' bonus levels involve getting a Maxim Tomato from a certain character—Chef Kawasaki in the first chapter, Max Flexer in the second, and Chef Shiitake in the third. If the Kirby(s) successfully beat any of these characters, they will get the Maxim Tomato, which heals any hurt Kirbys.
The Maxim Tomato is a recovery item in all the Super Smash Bros. games.
In the original Super Smash Bros., the Maxim Tomato heals a character of 100% of their damage percentage. In Super Smash Bros. Melee, Super Smash Bros. Brawl, Super Smash Bros. for Nintendo 3DS and Wii U, and Super Smash Bros. Ultimate, the Tomato only heals 50% of damage, due to the inclusion of the Heart Container recovery item from The Legend of Zelda series that also heals 100% (or all damage if the player is playing Boss Battles or All-Star Mode in Super Smash Bros. Brawl and Super Smash Bros. for Nintendo 3DS and Wii U) of the player's health. If a character is attacked while using the Maxim Tomato, it will "absorb" the damage. For example, if an attack does 30% damage, the tomato will absorb it and the user only recovers 20% damage. Like all other Super Smash Bros. items, it appears as a trophy in Super Smash Bros. Melee, Super Smash Bros. Brawl and Super Smash Bros. for Nintendo 3DS and Wii U. It also appears as a sticker in Super Smash Bros. Brawl, where the design from Kirby: Squeak Squad is used.
This bag contains some pretty special food. I can't tell you exactly what's inside, but if I pick one up, I will completely restore all of my vitality.”
Maxim Tomatoes cure 50 percentage points of your accumulated damage. Once you eat one, after a brief moment, your damage meter slowly drains the appropriate amount, regardless of whether or not you pick up another item right afterwards. In the Kirby series, these juicy, health-restoring items were a favorite of the pink hero.”
A juicy tomato that heals 50 percentage points of the damage you've accumulated. When one of these appears in combat, rest assured there will be a race to see who can reach it first. It's a race of desperation between players who want to heal their damage and those who want to stop them from doing so. In the Kirby series, Maxim Tomatoes healed all damage.”
A tomato marked with a large, black M. This is Kirby's favorite snack, and in the past it has fully restored Kirby's health. The ones that show up in Smash Bros. aren't from the same crop, though, and only heal 50 points of damage. That'll still help you in a fight—unless an enemy eats it first.”
The Maxim Tomato has appeared in nearly every Kirby game to date, either as an item, a cameo, or as an illustration.
It is unknown why exactly the name is Maxim Tomato instead of Maximum Tomato, as a maxim is a principle or rule of conduct, although in Latin, the word "maxim" derives from "maxima," which means "largest or most important".
The Kirby 64: The Crystal Shards instruction manual calls the Maxim Tomato a "miracle fruit" referring to it's healing abilities. Kirby: Triple Deluxe introduces an item actually called a Miracle Fruit, that gives Kirby the Hypernova ability.
