Doing your best to concentrate on the river you manage another few minutes of dodging tentacle trip lines so to speak. However coming around another bend in the cave reveals a two things. The first of which was a fork in the river where it split into separate rivers. The fork to the left seems to go downward more, the current becoming faster and near rapid like. The right fork meanders onward at a still faster but less drastically so pace. The second part about the right though is looking ahead to the next bend in that path you can see the glow of soft white light. Sunlight! If you could keep going that way, then perhaps escape was only a turn or three away!
The excitement of nearly being free again distracts you slightly however. Coupled with the slight increase in speed and the current darker area you were in makes in accounting for all the numerous tentacle pods difficult. You hit another one, but manage to use the same trick as before to dispatch it. Before you can recover your paddle though you hit a second and then a third. Another quick sidestep in the boat allows with the room to swing again, severing another whole slew of tentacles. The third set however comes from the ceiling directly above. You try to move but your earlier side step makes the rickety boat rock around in the water, making your footing unstable. Much to your chagrin a mass of tentacles suddenly ensnares you from above, quickly starting to coil around you, and make things worse, pinned your drawn sword arm to your side.
The things are slimy and warm, quickly coiling around your limbs and body and within moments seem to squirm their way under your armor and run across your bare skin. A couple second after that then they begin to lift, attempting to pull you out of the boat as they simultaneously molested you!
