Tunnels

You keep going into the disgusting sewer water to find your way out. Suddenly, the water gets much deeper and you go underwater. You then come out from under the water and you swim as fast as you can to land. As you are swimming you feel something touch your leg. It felt slimy and slobbery almost like an octopus. Freaked out by this you swim faster to land. You keep swimming until you feel it touching your leg again, then suddenly, the thing that was touching your leg, pulls you underwater. You scream and bubbles come out of your mouth. You realize that this water is very deep when you get pulled down further into the water. You look down at your leg and you see a slimy tentacle attached to it. You have two options to get out of this mess. Option one, you wiggle your way out of the tentacle. Option two, you yank the tentacle off with your arm. So, choose wisely
