The World's Biggest Tea party was a live show around 2007. It featured around 14 characters from the G3 movies, including Spike, Zipzee, Tra-La-La, Tiddly-Wink and even anthromorphic ladybugs. The show has a main story with the ponies and a bit of a side-story with Spike and the ladybugs. It was the only live show produced for the franchise and was rather long, longer than any of the G3 movies released before it.
Spike and the ladybugs are first to greet the audience and Spike asks the audience if they've seen his book. The ponies are then revealed with working eyes and moving mouths. A song begins that gets the audience introduced to each of the ponies. When it's over, the ponies still need an idea and sing again. This time, however Pinkie Pie realizes they have too many ideas to pick from and eventually decide on the world's biggest tea party. Since there's much to do before the party, each pony sings about their contribution. Later, things are coming together but Rarity hasn't brought the streamers she promised to bring to the party yet.
Spike still doesn't have his special How-To book that the ladybugs have kept hidden away. Worse still, in keeping everyone else in line, Pinkie Pie forgot her contribution, leaving the party without tea. With a little help from Minty, they come up with another idea and Spike finally gets his book that reveals how to have a tea party.
Each pony has animated eyes and mouths that sync up with the audio track that plays throughout the show. As the show progresses, the scenery changes and there's even sound effects to replicate being in different places. Each pony's hind legs are stationary and thus do not move.
Note: Song titles below are based on the lyrics performed by the characters in the show. They may not be the actual titles.
