Continuity mistake: The sardine tin that the ant uses as a piano has a rectangle in the middle of the lid at the start of his act. The rectangle disappears a little later on, but when the singer is hit in the face by a banana, it is back again.
Continuity mistake: When we see the two ants performing an act with the sardines tin, the tin initially has nothing on the side but in the next shot "Sardines" has appeared.
Continuity mistake: When the man picks up the sandwich that the ants have made, there is a cocktail stick with an olive on it. But when he takes a bite of the sandwich, the cocktail stick has gone.
Continuity mistake: When we see a man and woman sitting by a lake, the plate of pancakes on the picnic blanket moves from the left to the right between shots.
Trivia: On the picnic blanket, there is a dish of ice-cream with a cherry on top. Next to the ice-cream you can see a jar of "Frisby Pure Jam" - a reference to the Warner Brothers director Friz Freleng.
