Emerald gets the overwhelming urge to eat the goo for some reason, but abstains. Instead he brings the ooze to the attention of Joyride, who turns around and looks at his upturned hoof in curiosity.
"Oh, looks like we have a slime monster friend." Joyride says, poking the goo herself, examining it, and then wiping it off on the wall.
Emerald asks what she means by a slime monster.
"Oh, they come in all sorts of shapes and sizes. The fact that your leg didn't melt away just by stepping on it means it's one of the less dangerous ones. Hopefully. The slime is so old it doesn't even have any color, so I'm not sure which one it's from."
Emerald stares worryingly at Joyride, who just looks at him, and then turns away and says, "Anyway, forward!"
The pair of them keep moving, and the cave eventually widens into what appears to be a alcove that an animal was living inbefore leading off deeper into the ground. Bunches of leaves, twigs, and small nicknacks are formed into a bedding of sorts. There is slime everywhere here as well, but no sign of any creatures.
