Yoshi's Island: Super Mario World 2/Items

Special Items
These are items that can be earned for bonus and mini battles.

Watermelons

 * Super Green Watermelon: allows Yoshi to shoot seeds at his enemies.
 * Super Red Watermelon: allows Yoshi to spit fire at his enemies.
 * Super Blue Watermelon: allows Yoshi to spit ice balls at his enemies.

Stars

 * 10-point star: increases the timer by 10 seconds.
 * 20-point star: increases the timer by 20 seconds.
 * Anywhere POW: turns all enemies into stars.

Others

 * Winged cloud maker: turns all enemies into winged clouds.
 * Magnifying Glass: reveals the red coins.
 * Anytime Egg: refills Yoshi's egg maximum of six.

Eggs
Yoshi can collect eggs during the adventure. It can have up to six eggs (five if Yoshi is towing a Key). There are five types of eggs:
 * Green Egg: is a normal egg.
 * Yellow Egg: gives a coin if you hit an enemy.
 * Red Egg: gives two stars if you hit an enemy.
 * Flashing Egg: gives a red coin if you hit an enemy.
 * Giant Egg: turns all enemies into stars.

It is possible with clever aiming to improve Green and Yellow Eggs. A Green Egg that bounces once before impact becomes a Yellow Egg, and a Yellow Egg that bounces once before impact becomes a Red Egg (so a Green Egg can bounce twice to become a Red Egg). Also remember, if Yoshi gets his tongue on an egg in flight, he can reclaim it, meaning if there is a ceiling above Yoshi, he can shoot an egg upward and tongue it as it comes back down to make improved eggs that return to his stash.

Flower
There are 5 in each stage. Getting all of them earns a life, and each flower is worth 10 points towards the total score on the stage.

Red Coin
There are 20 in each stage. Each one is worth 1 point towards the total points for stage.

Star
The most you can have is 30. They increase the time that the player can leave Mario floating in a bubble if Yoshi is hit by an enemy. Each star is worth 1 of the 100 total points of the stage.
