Berserk Bear (Encounter 3)
The tunnel opens into a small, dimly lit chamber where the damp air is even heavier with the stench of rot. A large brown bear paces erratically near a shallow pool fed by the corrupted stream, its massive paws leaving muddy prints across the stone floor. The bear’s fur is matted and tangled with patches of mold, and its eyes are wild, bloodshot, and pained. It stops suddenly, turning toward you with a guttural growl. Drool tinged with a sickly green hue drips from its mouth, and it sways unsteadily as though the poisoned water has left it both enraged and confused.

Ooze’s Lair (Encounter 4)
As you enter the cavern at the north end of the stream, the air feels heavy, thick with a foul stench that seems to cling to your skin. In the center of the room is a strange looking rock in front of a giant brain fungus that pulses and twitches, oozing fluid into a shallow pool that flows into the stream to the south. Stirges nesting in the ceiling suddenly see you and attack.

Miner Difficulties

Adventure for Level 2 Characters

Situation. After miners dug into an Underdark tunnel, a Hook Horror found its way into the mine and became trapped. It has eaten a few miners, and the others are too terrified of the echoing clicks in the mine to hunt down the predator.

Hook. The mayor of the village of Blackstone, Kristryd Splitanvil (a Lawful Good, dwarf Tough), hires the adventurers—perhaps because of how adeptly they handled the situation in “The Fouled Stream”—to deal with the monster in the mines. She offers a precious topaz worth 500 GP to adventurers who kill the creature or drive it away.

Encounters

The adventure consists of these encounters.

Exploring the Mine. Use the Mine map in Appendix B. In the weeks since the miners abandoned the place, pests have flourished in the tunnels. Each time the characters enter a distinct area of the mine, roll on the following table.

Sounds of Terror. The first time this encounter occurs, the characters hear eerie clacking and scraping noises echoing in the mine shafts and notice gouges in the walls. The second time, they find the source of those sounds and markings—the Hook Horror. The creature is hungry, but what it really wants is to find its way back to the Underdark. It retreats from a fight that is going badly for it.

Underdark Connection. The tunnel in the southeast corner of the bottom level of the mine is where the miners accidentally connected to an Underdark tunnel. The hook horror entered the mine through a hole in the wall, but the hole closed behind it in a cascade of rubble. If the characters clear away the rubble from the hole, they hear clacking and scraping from the other side. The hook horror hears it too and hurries here to rejoin its kin. As long as the characters stay out of its way, it ignores them as it scrambles back through the hole, never to plague the mine again. Each character then earns a bonus 200 XP.

Roll #4 info https://www.dndbeyond.com/sources/dnd/dmg-2024/dms-toolbox#YellowMold

The party/adventurer(s) search by level 1, 2, 3 you have to go level 1 to level 3 to level 2.  Roll 1d6 each time you enter each level until you eventually roll 6 two times.

On the second roll of a 6 if you can roll a DC15 investigation you manage to release the hook horror to gain the extra 200xp otherwise it and it's family do the digging to get it back to where it belongs.  

The mayor of the village of Blackstone, Kristryd Splitanvil (a Lawful Good, dwarf Tough), hires the adventurers—perhaps because of how adeptly they handled the situation in “The Fouled Stream”—to deal with the monster in the mines. She offers a precious topaz worth 500 GP to adventurers who kill the creature or drive it away.

Yurk barters with the Mayor since he's on his own and asks for 2 antitoxin potions and 2 healing potions up front.  Who knows what's been going on down there.  Spiders and junk possibly. I'd to get a little safer going on my own please. Kryistryd nods and signals for the foreman to give them to Yurk.  "Good hunting."

As you can see rolling a 6 might not happen very often or not even twice in 16 rolls.  So I will DM that you do 3 encounters and then automatically get a 6 and then 3 more encounters and then an automatic 6.  This way you'll generate 6 random encounters in addition to automatically triggering the Hook Horror final encounter.  For enjoyment I'm going to run each encounter once and then roll a random 6th encounter.

1. Four Violet Fungi and one Rust Monster

2; One Giant Spider and two Swarms of Insects (spiders)

3. One Darkmantle and three Piercers

Auto roll 6 for first noise of the hook horror.

4; A patch of yellow mold (see “Hazards” in chapter 3) on a miner’s remains

5. One Gelatinous Cube

6  Random 6th encounter chance.

Second auto roll 6 to encounter the Hook Horror.

1. Four Violet Fungi and one Rust Monster

Yurk finds the dungeon and starts exploring the underground area.  He moves along on Level 1 first.  He spots something up ahead in the distance.
