The royal family happens to be incredibly unlucky. In session 1, my two children (girl 7 and boy nearly 5) had to rescue the Princess from a cave complex. You can read about it here. In session 2, now with cousins (boy 11, girl 9 and boy 7), the King was rescued. You can read about it here.

This snake just wants to eat!
The item might be in the room somewhere e.g. Pool in the room might need water breathing potion to be used, high shelf for levitating potion.
[The kids loved once again getting a magic item. I allowed quite a lot of freedom - they chose the type of item - shield, axe, wand, chain mail, bow - and I statted the item. Shield + 1 with protection from dragons (1/2 to 1/4 damage from dragon breath), Bow +1 with 10 +3 arrows, chain mail +1 (like Bilbo) with invisibility once per day, magic wand giving 2 extra spells per day up to third level - she chose two lightning bolts, axe +2 that always returns if thrown)].
[Party got initiative and did some damage, especially with lightning bolt. It breathed on my daughter but she had taken the protection from dragon breath potion she had chosen.]
