Hundreds of people came out to donate blood to the American Red Cross at the Adventure Aquarium on Sunday. Donations occurred right under a shark tank. Debbi Calton, Andre Gardner, and Ray Koob were all there to interact with the donors, and even give blood themselves. Debbi fed a hippo, and Ray befriended a penguin. The aquarium mammal's even took a few selfie's with the MGK jocks.
