Okay then: You can have Dwayne, we'll have to share custody of Vin, and I get to keep Jason Statham
I like to take a scientific approach to monsters. My daughter is now convinced that monsters are so scary due to a defence mechanism whereby they puff themselves up (like her bluey Lurch), to scare off potential predators (children) who they are convinced will eat them alive. She now feels sorry for them. She also knows how to turn off 'scary robots' (I googled electrical circuits and showed her that an interruption in electrical currents will instantly render any scary robot powerless, baw haw haw...), and that skeletons are just people without any muscles or skin, so they'll fall over as soon as you blow hard enough.
Not bad for a 4yo
Congrats Poggle! Just don't blink; as soon as you do they'll be older than you thought they were
