So I've just finished learning Penpersonship and rather than wasting my first writings trying to persuade glitches to give me chick cubimals, I made a simple mini-game instead. I wrote my first 10 notes, hid them all around Ur. What you need to do is find them and collect all 10. More details about the game is written in the notes themselves. The notes are named "Taupe's #'th Note".
Someone might have done something like this already... but I'm bored so that's that.
The prize for collecting all 10 notes is a bag of diamonds and a bag of moonstones. Nothing expensive since I don't have cubimals. I may add some currants to that but I'm not rich so don't expect much.
