Enter the secret room.

This room is hidden. It has to be full of treasure.

As Niki pushes it open and you all peek inside, you can see your dreams come alive. There are racks of iron weapons and armour down a lengthy room--approximately twenty feet wide but forty feet long. Shelves line the walls, which are mostly empty, but you spot a few shiny figurines and loose coins. Though the equipment looks mundane, and you don't want to carry back entire suits of armour, you can definitely find things to take back to sell for a pretty penny. The room itself looks worn, however. The walls are covered in large cracks, so you don't think you should linger for long.

Fortunately, it's lit as well.

The party hurries into the room, excited at the promise of loot. You each start grabbing a few things and stuffing them into pouches.

Suddenly, Amara gasps, and the party turns. You see a glob of green slime pop out from the crack beside her, and she scurries away. It retains some semblance of shape, though has no distinguishable features. It jiggles its way across the floor and slowly towards the party.

"Nuh uh!" Niki shouts as she slams her mace down into it. The slime splatters and ceases to be--the core in such a small slime being too tiny to matter.

You then look around in terror as more slimes begin popping out of the cracks. You have no idea what a green slime does, though knowing there are red ones that dissolve organic material, you don't really want to find out. There also seems to be quite a few of them, in many corners of the room. Even the exit is being blocked.

"Green, Eva? What's green?" you ask.

"I don't kn--Aah!" Eva shouts as one leaps into her behind.

Unlike the blue slimes that supposedly headbutt people to deal damage, this one splatters and engulfs her lower back. It start to ooze around to her front--spreading around her legs, and up her skirt. Though, it doesn't seem to be eating her skin nor her clothing. Right now, it doesn't seem to be doing anything at all, other than wrapping around her figure, and it doesn't look nearly big enough to cover her entirely.

"Get off me!" she shouts. "Gross... It's pulling up on my skirt." She pushes her hands down in front of her waist, but the green slime writhes beneath it. As she stands there trembling, unsure of what to do, her eyes widen as she gasps loudly.

"What is it?" Niki calls out moments before slamming her mace into another one nearby.

Eva pushes her knees together. "It's... It's in~!" She purses her lips and tries to hold back an embarrassing noise, and suddenly falls to her knees. She gasps again, and she can't hold it in anymore. A moan escapes through her mouth as she clutches at the slime between her legs. The skirt lefts, and you can see that it has worked its way all around her front, and beneath her panties, wiggling away behind the fabric and presumably inside. "G-Get it off now!"

"How do we do it without hurting her?" you ask frantically. "And what is it doing?"

"I think it may be feeding on moisture," Amara said quietly.

"You're kidding me. Uh. Eva! Stop getting wet!"

She shoots you a terrifying gaze. "How dare you!"

Her rage is cut off by the slime running up her stomach, between her breasts, and straight into her opened mouth. She falls onto her back as it penetrates both of her lips--tendrils of slime writhing inside her mouth as the other explores beneath, where her panties finally burst under the strain, and fall open between her legs. She jerks around on the ground as she's thrust into on both ends, and when she tries to pull it off, her fingers only glide right through. Her muffled moans pass through her nostrils as she breaths hard and panicked on the ground.

The must take some amount of damage from being hit. Like Nyllia said, only the giant ones have a visible core that can regenerate the entire creature. All I should have to do is snip it a few times to at least make it let go.
