As Numberland’s best detective, you thought you’d seen it all. But the desiccated corpses of prominent natural numbers have been showing up all over the city. A lockdown is ordered from sundown to sunrise, and it’s still not enough to stop what can only be described as a vampiric feeding frenzy. Can you figure out why the citizens of Numberland are being attacked? Henri Picciotto shows how.

Lesson by Henri Picciotto, directed by Igor Coric, Artrake Studio.
