"The Colour out of Space."

Does the stone turn back to normal if the Gibbering Mouther moves or dies?

The DM made us fight this thing in an abandoned library and for the first 2-3 rounds, I could not do literally anything. It stuck me in its's Aberrant Ground and then blinded me with its Blinding Spittle. Basically, put me out of the fight for a good few rounds. Eventually, I 3rd level Guiding Bolt it and incinerated it. Hands down, one of the coolest monsters to use but really annoying to be up against, especially if you fail all your saving throws 😭

Additionally, set this in a fairly tight dungeon, around a blind corner so the party basically runs into it. The mouther will hear them coming and get a surprise round to really put the party in a bad spot to start combat.

 No surprise round if the party hears the creature. And with a -1 to Stealth....

That depends on whether the party identifies the noise as hostile. My party will hear a room full of panicked party guests who've barricaded themselves in a room freaking out and bickering (following an attack by a coven of night hags). If my party believes that is actually a room full of panic stricken party goers and not the two gibbering mouthers one of the hags let into the room to devour them, just waiting at the door, the enemy gets surprise.

The DM just needs to make the sound a benign one. Unless someone in the party is letting me know they're not buying it (no roll needed, just on your guard) they walk right into it. That's how this thing hunts.

I just used one of these for the first time last night. No character took damage but for three tense rounds I managed to scare the living hell out of my players! They don't ever want to fight one again; awesome monster!

I threw two of these at my players and now they hate caves for some strange reason.

I'm doing a circus themed dungeon. Complete with Clowns, Mimes, and Rakdos Performers. This thing is going to be the muddled remains of a barbershop quartet that used to perform at the circus until there was a terrible fire which melted them together. Instead of murmuring incoherently they will sing in harmony. 

A Gibbering Mouther is always cool B)

Haven't seen this before! Nope!

I actually created a buffed version of this monstrosity for my player's displeasure. Its essentially the same thing except made of nerds and with joint glasses over all of its eyes feel free to check it out, its called a twaddling mouther. (twaddling is a synonym for gibbering.)

Nah, the gibbering mouther is alright, but have you seen the goon balloon?

What have you done.

WHAT HAVE YOU DOOOOOOOONE

In my campaign the PCs had just killed an allosaurus and left the corpse there, later in the dungeon there is a gibbering mouther i was thinking i could have the mouther absorb the dino and be an epic boss. 

If i did end up doing this would the stats be higher or lower then an allosaurus. because i would give it all the mouther abilities and some of the dinos so would it be to strong if a gave it normal allosaur hp. 

Looks like fecto forgo from kirby and the forgotten land. Many eyes, many mouths, both consume everything, and are equally terrifying
