Someone gave this can of Monster Ultra Watermelon to me for my collection.
I thought it was appropriate for the Christmas season since the can is red with green trim.
The person who gave it to me normally doesn't like energy drinks, but they said this one actually tasted pretty good. I guess so, watermelon flavor is usually good.
It's not an official "Christmas flavor," but I have entered it into my collection as The Christmas Monster.
