It's come back to me! I remember what happened! It starts off with the 4 sitting in an open field, then 4 men grow from the ground and carry the 4 into the castle. They show the 4 in the castle, then the 4 becomes all sparkly, and many wavy, sparkly lines go everywhere. They go back outside to show the castle sparkling, them 4 balls fly out of the castle turning into 4 unicorns, then the unicorns fly away leaving a small blue 4 at the bottom centre of the land.
