Yoto says: Shrink down with the BrainBots to learn all about the (superhero) immune system. BrainBots assemble!
Is it a bird? Is it a plane? No, it’s a white blood cell! The BrainBots are out of the classroom and shrinking all the way down to learn as much as they can about the cells that keep us safe - the immune system.

For one day only, join Nellie, Buzz and Gibbs as they head deep inside the body to investigate and become part of the superhero cells that fight germs. Viruses and bacteria are no match for the BrainBots!

Test your knowledge at the end of the card to see how many BrainBank facts you can remember about the human body and its immune system.
