Little Caesars (2023)
Three years ago, Little Caesars partnered with Pepsi to release a pineapple flavored Pepsi Cola that was available exclusively from the pizza chain. I wasn't aware of it at the time, what with the whole plague that was threatening to end the world and all, but I learned that they were bringing it back today and I wasn't going to miss out on it this time.
UPDATE [7/21/2023]: This soda made a damn good ice cream float! I made one with Pineapple Coconut Haagen-Dazs and used some pineapple rings as a garnish and it turned out very well.
