This morning I played in an online game of Delving Deeper with Cody Mazza of the No Save for You podcast. (He and I talked about Delving Deeper recently in a two-part episode.) Cody was running Greg Gillespie's excellent megadungeon, Barrowmaze, so I don't know whether to credit him or Greg with this idea.
The party is following the tracks of a rival gang of explorers. (The Bogtown Bastards if you must know. Curse their rotten hides!) We came upon a room at the East end of a hall, with an exit to the North. In the middle of the room (and filling most of it) was a huge quivering mass of flesh and several dead bodies. We needed to get to the door on the other wall, but were understandably reluctant to try and pass this quivering mound. I suggested tossing a body (slain in another room) into the corner opposite the wall we wanted to move to. When we did, the mass grew legs, stood up, shambled over to the fresh corpse and then dropped down on it. While it was raised up, we saw faces of other dead people in its belly. Yikes!
I named it Herbert Zamboni – because we plan to come back with a monster charm spell and use it like a zamboni to clean out the hallways for us. Even this time around we used it to polish off dead bodies so that they wouldn't reanimate as zombies, which is something that seems to be happening in the Barrowmaze. After leaving the dungeon it occurred to me that it might actually BE the thing turning corpses into zombies. Like maybe it eats corpses and poops out zombies. We'll see.
Anyway, I liked the fact that this encounter was either a monster or a trap, depending on how you approached it. We could have tried to fight it or burn it, but instead we decided to trick it. (I only had 2 hit points, so you had better believe I wasn't going to try and fight this bugger.)
I drew a picture of Herbert later. At the last second I added some subtle/weird eyes. Or are they nipples? Or maybe both - eyples that lactate milky tears. Shrug.
