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.
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.
