Spin a bedtime scary story ... as told by a dragon to his nest of hatchlings. What do dragons most fear? What do kid dragons most fear? What are the monsters-under-the-bed for dragons?
That idea could extend to other dads: werewolf, sea monster, vampire, ghost, orc, monsters under the bed ... What are monsters-under-the-bed for monsters-under-the-bed? You could write a whole series of short monster stories.
