It is night, and the Smurfs are all going to bed. Dopey Smurf runs yelling that he has seen a monster, but no one believes him. A few moments later, a giant bird whose call is "Booglooboo" comes and destroys Papa Smurf's roof by accident. Papa Smurf assures them that it is an exotic bird migrating south for the winter and it will not come back. Smurfette realizes that if it is going south, it is heading towards Gargamel's home.
