SONIC to launch Blue Pelican Slush across Louisiana to support waterway preservation

All 138 SONIC Drive-In locations in Louisiana will begin serving the ‘Blue Pelican Slush’ starting October 1. The drink, which features Sprite, blue coconut flavoring, and sweet cream, was created by Lieutenant Governor Billy Nungesser in collaboration with carhops at the Amite SONIC.

The promotion is designed to raise awareness and funds for the Keep Louisiana Beautiful Foundation’s ‘Love Our Waterways’ project. Proceeds from the slush sales will support efforts to prevent marine litter and maintain the cleanliness of Louisiana’s waterways and communities. The statewide rollout follows a successful local partnership that began in 2025. A special celebration for the launch is scheduled for October 8 at the Siegen Lane SONIC in Baton Rouge.
