"We are simple Followers, lost in an unfamiliar place," says the robed ???mushroomfolk???. "The great Sozo sent us to find more of his beloved Menticide Mushrooms."

The Lamb frowns slightly, trying to puzzle out what the word 'Menticide' adds up to. Something about poison, maybe?

"He cares only for mushrooms. His madness grows! But when we arrived, we realized we don't know how to find Menticide Mushrooms... and now we are too afraid to return empty-handed. If you were to bring him Menticide Mushrooms, he would certainly reward you. You will find him at Spore Grotto."

That sounds like a problem that is not her problem.

"I'll... keep that in mind," she says vaguely. Some foolish impulse compels her to add, "Though I don't actually know where that is."

The mushroom people consult with one another for a moment and then draw a crude map in the dirt with sticks.

It's enough for her crown to get a fix on, though she doubts she'll ever use it and in fact kind of hopes she doesn't.

"Thanks. Good, uh, luck."

Onward? Onward.

Cultists, angry frogs, an enormous pile of gold for some reason, Clauneck with some new cards she hasn't seen before, aaaaand a clearing with a pentagram drawn in the ground, its points each adorned with a burning red candle, heaps of bones piled in its five arms.

"Yeek," she says, beholding it from a safe distance.

The pressure of the Bishops' presence descends, and the Bishops rise from their black pools on the ground: the shark-faced one with the round blue crown-eye and the froggy one with the triangular yellow crown-eye and a third one, that she hasn't seen before, whose crown-eye is a purple crescent like the one on the fourth door.

"Five points to a pentagram, five portents of doom, five siblings stood abreast, five Gods and one tomb..."

"Shamura! We did not wish to bother you, but—"

"Shamura, the Red Crown grows stronger by the day. Already it has succeeded where he has failed before. Leshy has been slain!"

"Five becomes four becomes three becomes two becomes one becomes nothing."

"...Shamura, rest. We will deal with this. Won't we, Kallamar?"

"Yes, sister! Of course, sister!"

The pressure lessens enough that the Lamb stops levitating.

"You there, vessel of the Red Crown! Bow to me, or you will regret it!"

She picks herself up from where she fell, then grits her teeth and stays standing. Is the froggy Bishop going to curse one of her cultists again? No, even a threat that dire wouldn't be worth giving in to. She has her crown and she's going to kill all these people.

"You will bow, or I will make you!"

Something happens, a breaking wave of intensity crashing silently over the clearing, breaking the bones on the ground and snuffing out the candles. But, as the Bishops descend into their pools of darkness, it is not at all clear what.

Well, she's not dead, so she'll take it. Time to get a move on.

The rest of the forest is remarkably devoid of anything other than hostile frogs.

It gets to the point where she's wondering if she's been cursed to roam the mushroom glades eternally battling their amphibian denizens, but what is there to do other than slog onward? At least the hostile frogs have lots of lovely bones for her crown to pocket.

At long last, though, she comes upon a stone-floored ruin inhabited by an awful-looking bat creature covered in weird pustules!

Sounds about right. Murder time!

Fighting the bat-thing is mostly pretty straightforward except for one minor detail, which is that when it races across the floor leaving a blazing wall of fire in its wake, the fire spreads out from that trail, such that the only safe place to stand is where it has already passed.

Well, that's one painful and embarrassing mistake she won't be making twice. The next time it does that, she dives straight through the wall of flame instead of fruitlessly trying to keep ahead of it.

And when she beats up the bat-creature, does it turn into a monsterfolk and beg her forgiveness?

Yep, totally does.
