Going down the list of everything they have done while crusading for cutie marks, Sweetie absentmindedly realizes that she has no idea what kind of tree Twilight lives in! What better way to crusade for cutie marks than identifying different trees around Ponyville?
Nothing could go wrong, right?
Crossover with the Monument Mythos series on Youtube. If you haven't seen it, I highly recommend it. No spoilers in the comments. Viewership of the Monument Mythos is not required to read this story. This story was heavily inspired by "ROCKEFELLERTREETRAGEDY".
