6+: Yes you snag her.

At first she thinks it is a part of the game. She is fast and hard to catch but you stick with her, going after her relentless and hoping she would tire or make a mistake. She gleefully continues to do her disappearing trick but you eventually get the better of her and grab onto her roughly.

"BLEEEEE!" She squeals in terror at the brute treatment.

Her warm slimy body shifts and squishes and slips easily through your fingers. But you knew there was one part of her that was solid, the only part you really cared about. Twisting your hand you grab onto the ruby embedded in her head and tear it from her with a plop sound.

(Add 1 Ruby to your Items.)

She disappears down a hole. You don't see her again. You flip the gem triumphantly and stick it in your pocket. You turn on your heel to leave this silliness behind you and leave the room.
