Continuity mistake: When Spinelli arrives at school at the end, she holds her purse in her hand, but it disappears two shots later. It reappears when the gang starts to play tag.
Other mistake: When Spinelli sees the man walking multiple dogs, as she asks him how much he gets paid to do it, the poodle's chest fur becomes the same colour as the background twice in two frames. The same thing happens with one of the Dalmatian's legs.
Continuity mistake: When Spinelli and Pat Patterson sit on the bus bench, the text on the bench that says "Just Buy It" has a period at the end, but the period is missing in all the following shots.
Continuity mistake: When Pat Patterson tells Spinelli that they should have a seat on the bus bench, the bench is missing the word "Gumoflex" and the black gum logo that it had in a previous shot. They both reappear when Spinelli and Pat sit on the bench.
