The scary and fascinating truth is that octopi are among the most intelligent creatures on Earth and they're watching us or worrying about numbers like in Heart Calcopus.

You need to impress the octopus by showing a base mastery of numbers and being able to do calculations as quickly as possible. They won't be overly complex, but they'll still test your general math knowledge and whether you can reach solutions quickly and pop all those number bubbles.
