Kick the eyeball

As the mouther's powerful tongue drags you towards its mouth you wait until the black orb of its eye, waving atop a fleshy stalk, comes into range. With all of your strength you lash out with a foot. You shoe sinks into the yielding gelatin of its eye and pulls out with a gush of disgusting fluid. The mouther's tongue immediately unfurls form around your waist and the creature howls with rage. You nearly fall straight into its open mouth, but you turn at the last moment and tumble down its body to splash into the shallow water.

While it is grabbing at its blinded eye, you turn and run in the opposite direction of Frankenstein and his gang. You head towards shallower water, kicking up the filthy liquid behind you. The shore and an escape are still a good distance away when you hear the mouther roar with new purpose. Glancing back you see the muscular monster start after you, powerful legs churning the water, claws outstretched to seize you and huge, shovel-tipped penis bobbing obscenely up and down with each stride.

The mouther is faster than you, its strides longer, but you feel like you can make it to the far shore and escape from the pool, the mouther and Frankenstein all at once. Your only alternative is diving into the deeper water and hoping you can somehow elude the creature. The pond is churned from the running and fighting and it might provide a cloud to conceal your escape.
