Speedy Beaver

Speedy Beaver is the bus that transported Dipper and Mabel to Gravity Falls.

History
The Speedy Beaver bus line is the vehicle that drove Mabel and Dipper to Gravity Falls at the start of the summer.

In "Gideon Rises," a Speedy Beaver bus with Soos as its driver is seen taking Mabel and Dipper home until the Gideon-bot starts to persue them. After caching up to them, Gideon uses the robot to rip off the roof of the bus.

Appearance
It seems to be a light blue bus, and on (presumably) both sides are two stripes, one dark orange and one light orange, and then in the stripes is white, giant letters that say "SPEEDY BEAVER," and an orange beaver with a pink tail running to the left, leaving a streak of stripes with the same shades as the others.

Trivia

 * In the animatic for the theme song, "Speedy Beaver" is named "Fast Dog."
 * The bus that nearly takes Dipper and Mabel away in "Gideon Rises" is #52.
