Next week, I'm going camping with my wife, my brother and his wife, and my 9-year-old niece.. My brother asked if I'd prep a DnD game to play. My niece knows the basics and I'm modifying rules to make it easier for her, and I'm making a bunch of characters for them to choose from based on Gravity Falls characters.

I'm prepping A Wild Sheep Chase for playing out in the fresh air, but we have a chance of rain I'd like suggestions for another short adventure i can prep. The sillier the better!

My friends and I recently finished a campaign and are having session 0 for Ghosts of the Saltmarsh. My wife challenged me to create a character who's not angry, so I want to play a small race mad scientist Armorer Artificer who rides around in a suit of armor like a magical mech. Which small race would I pick to maximize the fun of this little chaos gremlin?

Edit: We're playing 5e2014.

I was wondering if there's a way to view all of the communities on a server other than the one i signed up for. If not, would it be possible to link the instances' names to their communities list?
