Perry the Platypus is the pet platypus from Disney's animated series Phineas and Ferb, which premiered in 2007. In the show Perry secretly works as Agent P for the O.W.C.A., and his appearances are often marked by this distinctive low-brass sting and the chattering platypus sound. Clips of the cue spread through fan edits and soundboards as a shorthand for a character suddenly appearing or switching personas, and it remains a popular nostalgic cue among viewers who grew up with the series.
