In a chaotic internet crossover, Liquid Death and MrBeast teamed up to transform that classic chocolate and peanut butter flavor into a limited-edition sparkling water. The drink tastes exactly like a liquid Feastables Peanut Butter Cup, just with a fizzy twist. The peanut butter flavor hits you immediately. If you consider yourself a peanut butter connoisseur, it is 100% worth a try. It tastes remarkably close to a real Feastables Peanut Butter Cup.
