Ice watermelon

Super Blue Watermelons (also called an Ice Watermelon) are cold and frozen blue Watermelons (with blue skin, red flesh, and black seeds) found in Super Mario World 2: Yoshi's Island, its remake Yoshi's Island: Super Mario Advance 3 and its sequel Yoshi's New Island. If a Yoshi eats it, he will be able to breathe three blasts of ice. The ice can freeze enemies solid, which can then be smashed to pieces. In Yoshi's Woolly World, enemies that are frozen will slide along the ground when touched by Yoshi.
