I was a young DM, just doing my best. I was confident I knew the rules well, but previously I had only lightly dabbled in item creation, while mostly following pre-made books and adventures. However, this was a holiday session, so I wanted to step out of my comfort zone to create a fun and interesting session. Candyland was created!
The regular group had been left in the bottom of a dungeon during their last session. They had spotted a massive rat wearing a strange outfit, chased it, and ran into another character, Dana. Dana did not normally play D&D, but wanted to join our Friday night escapades.
Elvu, Zirq and Wuufy quickly grouped up with Dana and followed the rat into a dark cavern. They emerged in a Willy Wonka-esque Candyland.
