The cereal will first arrive at Sam's Club, which managed to wrangle a 30-day exclusivity period for the launch.
The cereal features "berry fin-tastic" flavored rings and marshmallows. Unfortunately, the marshmallows are not shark-shaped.
Sam's Club will carry a 26.4-oz two-pack of Kellogg's Baby Shark cereal for $5.98.
Other retailers will get the limited-edition cereal around late September.
