Set in the 'Youngverse'

One day whilst out practising, Luna gets spooked by a butterfly and accidentally sends it to the moon. Running high on giddiness at her new power, she decides to play several pranks on her sister Celestia.

Surely nothing bad will happen, right?

The first story from Luna's and Celestia's childhood in the 'When they were Young: Luna and Celestia trilogy'.
