Update: We tried it! Click here to read our review.
It’s not marshmallow flavored. It’s watermelon strawberry flavored. It’s also available in a Zero Sugar version. If you want a marshmallow flavored Coke, just buy a Vanilla Coke and repeat after me, “This is a marshmallow Coke. This is a marshmallow Coke. This is a marshmallow Coke.” (Spotted by Holly at Wawa.)
