Twins Scarlett and Thomas have been learning about the Maya at school.
They even had a go at making hot chocolate from cacao beans.
When Grandad falls ill, the twins know what the perfect cure will be – hot chocolate!
They nervously borrow Grandad’s time machine and travel back to the time of the Mayas.
Scarlett pretends to be a god, and gets taken in by the royal family.
Thomas is not quite so lucky, and ends up playing for his life in a brutal Mayan ball game.
Watch out, Thomas, if you lose, you might be sacrificed to the gods!
How far would you go to find the best hot chocolate?
