Botany Bay is a traditional folk song about convicts transported to Australia, long associated with sailing and emigration, and its melody has been reused in film and television for generations. In SpongeBob SquarePants it appears as cheerful incidental accordion music, helping Bikini Bottom feel like a real seaside town. Fans collect it alongside other familiar SpongeBob cues like the spongebob sad song and running gags built around the My leg! cry, using each short sting to set a scene instantly and trigger recognition among viewers who grew up with the cartoon.
