Continuity mistake: At the part where Howie is in the neighbours' house "stealing" the Turbo Man the head of a statue catches on fire. He tries a couple of times to get the fire out. In one shot the head is right next to his foot and in the next shot the head is gone. Then in the very next shot the head is back and he kicks it out the window.
Revealing mistake: Certain parts of this film were made during the spring months, not winter. In the background of the high up shots during the parade, leaves can be seen on trees (in the distance). Also, the grass is surprisingly very green, in several locations.
Continuity mistake: Myron and Howard are in the restaurant while Myron is drinking an uncapped beverage. During their conversation, the camera cuts to reveal the bottle now capped.
Continuity mistake: When turbo man takes of his helmet at the end, his head gear has completely changed, he is no longer wearing the pink neck collar or head covering, or the bits that cover his ears that match his costume, he is wearing a normal helmet.
Continuity mistake: When the cop salutes Turboman at the parade, the coffee he spilled on his gloves minutes earlier has mysteriously disappeared, as have the marks all over him from the explosion earlier.
Revealing mistake: The parade is supposed to take place around Christmas, but in some scenes looking down from above, we see very short shadows under the floats and people (indicating filmed during summer). At Christmas, shadows are long all day especially in Minneapolis.
Other mistake: When Howard, as TurboMan, is stuck spinning around in the sign at the end, the parade crowd disappears.
Continuity mistake: Howard arrives back at his home in a tow truck. It is obviously late in the day judging by the sun angle. In the next scenes however it is afternoon. The parade takes place in bright midday sunshine.
Other mistake: When Howard is running behind the car driven by the lady in the fur coat, he's always shown directly behind the center of the car, but when the lady looks in her side mirror (from her point of view), Howard is in the center of the mirror. In reality, she would only see a part of Howard's left side in the reflection (not his whole body).
Visible crew/equipment: When Howard first pulls into the empty lane, a camera shadow is visible on the car.
Continuity mistake: When Howard is trying to stomp out the fire, in some shots, the fire appears to be in a different spot than the previous shot.
Visible crew/equipment: Right before Turboman runs into Booster, the camera is showing his point of view. Its shadow, with wires etc. can be seen on one of the men moving the lift.
Answer: Most likely, she decided to keep it and not want to give it to Howard which is why she put it in her mouth.
