When my grade-school-aged son wanted to play an 'Intro to D&D' module, I hijacked a Zelda castle and filled it with random D&D monsters. Including bats in the caves underneath. The Boss Monster was ... a Skeleton Dragon. It sat in its lair - a huge 'nest' made up of all sorts of bones - and started off with its "breath weapon": a string of knuckle bones! I described the small bones being sucked up from the 'nest' as it inhaled, then passing through where its throat ought to have been and out between the jaws.A dragon is an amalgam of every predator our tree-dwelling ancestors feared.
My son was playing a group of 4 PCs (Basic Rules, L1 Magic-User, Dwarf, Cleric, Thief) and we both found out the power of magic items when the Cleric, equipped with +1 Chain Armor and a +1 Mace of Skeleton-Smashing (because Link's power-up items in a castle always have something to do with defeating the Boss Monster), rolled a crit (I said "he winds up a haymaker") and did twice as much damage as anybody else, plus being nearly-unhittable. The rest of the party could not say the same...
