Right after jumping in the goo, you hear a voice:
You are kidding me. Did you really think there was an exit door or something else down there in the goo? Man, you must have brain damage. Goo will always be goo. It's like jumping in a volcano to find a hidden treasure. If you like those kinds of deadly treasure hunts, call The Doctor. He'll certainly allow you to go back in time with a machine that's bigger on the inside to meet the pirates. By the way, i think you're dead, right? DO YOU HEAR ME? Hello?
