watermelon beachball
A beachball designed to look like the outer green rind of a watermelon.
This shouldn't be used if the ball has green patterns similar to what a watermelon looks like, such as post #117985 or post #98446.
Sometimes a watermelon will be present alongside with another distinctly colored/patterned beachball. If you can't tell if the watermelon is a beachball as well, don't use this tag, and use watermelon instead.
