Two days later...
The Wonderbolts were first to arrive, at 10:00, AM sharp. Then, several others began showing up: Neighsay and his rescue mates, Luna and Celestia, Sunburst, The Changelings, Gilda, Ember, The CMCs, Cadence, Shining Armor, Flurry Heart, and many others.
Finally, Twilight's parents arrived at the castle, and everyone got ready. Twilight blindfolded them, had them place a hoof on her back, and follow her inside.
"What's this all about, Sweet Pea?", asked Twilight Velvet with a curious but excited tone.
Twilight opened the doors to the party room and gave a nod.
Rainbow Dash got ready with the lights, and Fluttershy closed the doors as Rarity took off the blindfolds.
"What is going...", Night Light started.
"Now, Dash", yelled Twilight, and the lights flashed on.
Everybody yelled, "SURPRISE, HAPPY ANNIVERSARY!!!"
"Woo Hoo", shouted Twilight Velvet, "This is great."
Then, Pinkie's party cannon fired off, signalling the start of the celebration.
