The Sunshine Smoothie is a mixture of banana, orange juice, mango and pineapple.
This promotion is an annual fundraiser for Camp Sunshine, a free, year-round retreat located in Maine that gives children with life-threatening illnesses a chance to enjoy recreational activities as well as medical and psychosocial support.
Tropical Smoothie Cafe has raised more than $5.3 million for the camp since 2007.
