The Mystery

The Mystery is the one-hundred-ninth episode of Numberstairs.

Story
Infinio and NS-18 go on a walk. Later, Infinio goes to the grocery store to buy milk and flour. And then he continued his walk with NS-18, but, by the time he came back, NS-18 had teleported to Ancient Greece to find her identity. He runs and tells Detective Pie about the mystery. Pie reports a problem, also. She said she went to buy a cake for her brother Tommy's birthday, and then put it in a bag, and then, when she got home, she looked in the bag she put the cake in, and it was gone. Toxy reads the newspapers about these two mysteries, and when she finished reading them both, she really loved that those two things happened. Toxy celebrates by dancing with Notty and playing Three Caballeros music. And then later, a shadow appeared in front of Infinio's door. Infinio found out it was Millyrain. He waves at her, and then leaves. And then True is seen skylining near. Toxy sees it, and tries to jump up there, also, but fails. And then Numberblock Seventeen is seen painting True skylining. Do Re Mi Mouse sees that, grabs the paintbrush because Seventeen dropped it, and tries to paint something but fails because the canvas is too high up. And then later Jay comes and says "What's going on in here?".
