_cpzh4: Like some people use special whistles to attract birds, your task is to create an 30 second or less audio file that might be used to “call” a particular character from a movie, tv, or real life. It cannot feature voices, but sounds only (try http://freesounds.org).

Write a description why this sound would be attractive to the character, why it would be effective (be inventive, write a story about it).
