Road Trippin - S1.E16

Granny Smith drives the Rainbooms' tour bus to their scheduled appearance at Goldie Delicious' party. Along the way, Granny takes a "shortcut" past a traffic jam, Applejack and Twilight fix a flat tire, Fluttershy redirects a herd of cattle in the road, and Pinkie Pie clears away a fallen tree with her explosion powers. As the bus drives toward a broken bridge, Granny speeds up and goes through what is actually a movie set. The bus finally makes it to the party in time for Goldie to introduce the Rainbooms to the stage.
