Stan’o’war

The  is Grunkle Stan's fishing boat from The Legend of the Gobblewonker.

When as Stan is untying it from the dock, in preparation to go fishing, Dipper and Mabel ask Stan if they can use it in their hunt for the Gobblewonker instead. After they decide to search with Soos on his boat, Stan goes about the day in solitude, annoying many other fishers.

After Dipper, Mabel and Soos learn the alleged monster was just Old Man McGucket in a robot, they ask Stan if they can come aboard, since their ship has been destroyed. A series of photos of the four enjoying themselves in the boat is shown, and finally Dipper and Mabel relaxing as the group drives off the lake.
