This is tied to the Watermelon homework assignment. I've been working on a version of this for a bit, and just got it like I wanted it. The homework timing was a happy convenience. This is not the traditional coconut-heavy snow cone tiger blood, I actually wanted the watermelon up front.

TPA Coconut: I used this instead of coconut extra because I wanted the watermelon to be the star of the show. This lends just enough coconut flavor to know it's there.
TPA Dragonfruit: Accents the strawberry and adds a touch of juiciness to the mix
TPA Strawberry: I didn't actually try any other strawberry flavors for this. My worry was that any other would either be too sweet, too strong, or too pink for this. I may do a version of this with Straw Ripe just to see what happens.
PUR Watermelon: This is the watermelon I've been looking for. Sweet and candylike without the qualities that annoy the hell out of me in TFA watermelon. I did a batch of this with CAP double watermelon as well and it was okay, but this tastes better and more well-rounded to me.
