I haven't seen this episode, but I know it was the tree.

Yes! Dungeon Delve! I’d love to see White Plume Mountain or Tomb of Tomoachan next!

Hell yeah more dungeon delve!!

I did the sunless citadel with my wife and our two kids. Mepo died and they were so sad (kids) and mad (wife) that I had to "go back in time"... 😅

Just finished watching the Tomb of Horrors one for a second time, so excited! Love this series
