Watermelon

Watermelons are fruit that appear in several games of the Mario series and differ from game to game. They are based on the real-life fruits and strongly vary in size. Watermelons appear mainly in Yoshi series, along with many other kinds of fruits.

Yoshi series
In Super Mario World 2: Yoshi's Island, its remake, Yoshi's Island: Super Mario Advance 3 and Yoshi's New Island, there are three different types that offer special attacks. Super Green Watermelons allow a Yoshi to spit out the seeds as projectiles; if it already has a bite mark in it, there will only be a third as many seeds. Super Red Watermelons allow three shots of fire breath that burn enemies and melt Ice Blocks. Special Blue Watermelons allow three shots of ice breath that freeze enemies, making them harmless and immobile and causing them to break apart when a Yoshi touches them.

In Yoshi's Story, Watermelons appear as the favorite fruit of Green Yoshis, along with Melons.

In Yoshi Touch & Go, Watermelons, when eaten, give Yoshi five eggs.

Super Mario Sunshine
In Super Mario Sunshine, massive Watermelons appear. In Gelato Beach, the Surf Cabana makes Watermelon smoothies, and there is a Watermelon Festival to show off the person with the largest Watermelon. The Watermelons there are quite sensitive to pressure, and act and look more like water balloons. In the secret levels & Pianta Village, Watermelon Blocks can be found, which act as breakable Blocks.

Super Mario Galaxy / Super Mario Galaxy 2
In Super Mario Galaxy and its sequel, when 9999 Star Bits are collected, all the green coconuts in the game turn into Watermelons. In Super Mario Galaxy, a Watermelon is featured in the "Bubble Blastoff" mission in the Deep Dark Galaxy. Mario lands on a glass planet where he must Ground Pound the three encircling tennis balls within the planet which will hit the Watermelon in the center and cause it to grow visibly larger until it shatters the glass planet and becomes the new planet.
