Beginner friendly module/dungeon

Hello! I have been put in charge of our next family gaming night, and I thought I could introduce my 9 year old daughter to the greatest hobby of all. Since she loves fairies, I will be running OSE with a little class reskinning: druid will be earth/forest fairies (dryads), elves will be fire fairies (salamanders), magic-users will be air fairies (sprites) and clerics will be water fairies (nayads).

Do you guys have any suggestions of modules and/or dungeons I could run that would fit the sensibilities of a 9 year old girl?
