Taco Bell is bringing back its seasonal watermelon-flavored slushy drink. For a limited time only, the fast-food chain will offer the Watermelon Freeze at participating locations nationwide.

The ice-cold beverage, which first made its debut last summer, comes with black candies that are meant to look like watermelon seeds mixed in. The "seeds" are completely edible, but Taco Bell warns that they could be a choking hazard and that the slushy is best suited for anyone above the age of 4.
