From publisher blurb:
A group of young adventurers are on the trail of the White Rabbit! After falling down a strange hole and running the oddest obstacle course ever, they finally catch sight of the White Rabbit just as he runs into a strange castle filled with quirky challenges that make a perfect first dungeon. Welcome to Adventures in Wonderland, a mini-adventure path for Dungeons & Dragons Fifth Edition! A Message for the Duchess is a family-friendly mini-adventure suitable for 2nd level characters.
In the first three chapters of Adventures in Wonderland, the party chased the White Rabbit through the wood and rescued it from a nasty tangleme tree. Proclaiming they were all late, the rabbit used its plane shift ability to transport everyone to the top of a deep rabbit hole. In the rabbit hole, the party had to feed words to a singing dictionary, catch a peek-a-boo, and drink a potion to make them small, all so they could fit through a tiny door and run a strange obstacle course prepared by the Dodo!
