Ice watermelon

Special Blue Watermelons are blue Watermelons found in Super Mario World 2: Yoshi's Island. They may be cold, but it is uncertain. If a Yoshi eats it, the dinosaur will be able to breathe three blasts of ice. The ice can freeze enemies solid, which can then be smashed to pieces. In the Game Boy Advance remake, Yoshi had to freeze two Tap-Taps and leap off of them to access an otherwise unreachable area in Level Special 5, Items are Fun!
