"Cave Johnson here."

The elevator gave a jolt, age-old pistons going back into action, sending the machine up. It jittered and shuddered slightly on its voyage.

"Well done. The fact you've survived the mutant mantis men army is quite a feat. The lab boys tell me it was a 99% chance of death. In simpler terms it just means you shouldn't have made it out in the first place- congratulations!"

Continuing up the elevator made no sign or gesture towards the voice. The voice however acted as if the elevator was actually listening. It crackled slightly, the speakers wearing out.

"Now, if you've suddenly noticed that any limb that was previously missing has suddenly started to regrow back, don't worry- completely normal. We've just injected you with starfish DNA as you entered the elevator.

"You may feel slight tinkling sensations in your arms and legs- that too is normal. But if you feel it anywhere else- that is not normal. Contact one of the lab boys as soon as possible."

The elevator gave a very sudden jolt, stopping in its path. The doors creaked open, revealing empty space inside. The voice once again began talking unaware of its surroundings.

"Cave Johnson here. How would you like to join an army to defeat an army of mutant starfish men?"

A silly idea I put together in a day. No idea where it came from.
