Squeaky was a little mouse and Smurfette's pet who was so named because he made squeaky noises. His only appearance was in the episode "Squeaky". He was found sick by Smurfette and was taken to Papa Smurf, who managed to cure him. He and Smurfette had some good moments together until it was the time to go back in the forest, but for Smurfette's happiness he decided to stay with her. On the last night of his life, a fire was started at Papa Smurf's house which Squeaky had noticed and awoke Smurfette to alert her of.
