A few more Halloween cartoon cliches:
- The characters often get from trick-or-treating full-size candy bars, popcorn balls, homemade cookies, and other stuff people don't give out anymore in today's "snack-size" candy bar/"safety first" era.
- The candy often is often proclaimed to be enough to last for weeks and weeks on end, yet either A) the characters manage to eat it all in no time flat or B) they never mention in their Thanksgiving/Christmas specials still having a truckload of candy sitting around from Halloween...
- Characters never bother checking their candy to see if it's safe or anything, and often start chowing down on it while still going from house-to-house. Yeah, they're cartoon characters, but still (throw this one on the "characters setting bad examples" list, too ;-) ).
- An adult/older teenager will often dress up to go trick-or-treating (see: Homer in the first Simpsons Halloween special, or Kuzco in "Emperor's New School").
- Characters often are allowed to go trick-or-treating by themselves, even if they're rather young children. Granted, so did I often as a kid (with my younger siblings), but it was a more closeknit neighborhood/different times...
Excepction to the second one: the "Peanuts" Thanksgiving special, where upon learning it's Thanksgiving, Sally notes she still hasnt' finished off her Halloween candy.
Re: cold weather on Halloween: The "Peanuts" Halloween special also addresses this---by showing Linus shivering from cold sleeping in the pumpkin patch when Lucy gets up to get him early on November 1st.
