Novelty flavored protein powders

Options
I've been alternating between Designer Whey Chocolate and French Vanilla. I'd like to try some other flavors! I always use frozen spinach in my smoothies because I like the bulk it adds. I've been using a fresh banana for sweetness, but am open to other fruit options. I've tried pureed pumpkin and vanilla protein powder with pumpkin pie spice and it was pretty good. Not really a summer flavor, but tasty nonetheless.

Any yummy, novelty protein powder suggestions??
