The goo slams into your back, the behemoth of a beast letting out an almost laughing-like shriek. You shout, trying to stand, to flee, but fall, coughing up slime. Something starts to grow from your side, twisting and clawing at the floor as you thrash. A heavy form sprouts from your tailbone, legs melting and twisting into something more animalistic. More limbs are growing from your sides, trying to assist you in sitting up.
Your head spins, the giant beast's laughter echoing in your head as you leave your human form behind.
