You bet! Some include:
-Ice cream (generally a constant but still topical)
-Slushies (fruit flavors primarily, but the soda ones are great too!)
-Milkshake stuff (also a constant, but hits different in the summer)
-Lemonade (with lots of sugar!)
-Candy put in the freezer (it works, sometimes!)
-Generally cold sweet stuff
Lots of possibilities to choose from!
