The bus of Bikini Bottom is a public transportation vehicle that appears in various episodes, starting with debut episode "Help Wanted."
Description
Design and boarding
Bikini Bottom buses are red in the series, but the LEGO set version is orange. They also have porthole windows and periscopes on the top, giving them the appearance of a submarine with wheels. It also resembles the look of a shrimp, while the rear end of the bus represents a fish's tail.
Typically, most of its passengers are regular Bikini Bottomites, though other animals are also allowed to board the bus, as shown in "Dumped," "Have You Seen This Snail?," and "Pet or Pests." Most buses seem to have a "no singing" policy, as seen in "A Flea in Her Dome."
