'Hey kids! We've got this film about a puppy to watch,
There was one before it that we haven't seen yet, but this is set before it so we will watch this first."
After watching this - "Hey kids, let's watch the first film, I bet it's as cute, cuddly and heartwarming as the puppy in that last film we watched."
During watching it - "Daddy, why is Marley sitting under the tree?" "Why is he getting that needle in him?"
Afterwards "Waaaaaaaaaaaaaaaaaaaaaaahhhhhhhhhhh!!!!!!!! The cute puppy is dead! That would never happen to an Air Buddy!"
This will happen everywhere.
