Based on a French comic book by Lewis Trondheim, Fly Tales is a French and Canadian animated series of shorts, featuring the adventures of a young, curious, troublesome fly in different environments. In most of the shorts, the fly would get himself into some trouble, but always finds his way out of it somehow.
The Factory (E27)
While inside the soda pop factory's laboratory, the fly finds some experimental ingredients. Upon eating a red one, the fly inflates and flies around like a balloon.
