Immersed in an enhanced psychic state, Eleven scoured the Upside Down to find Will Byers and Barbara Holland. She discovered Barb's corpse and saw a slug-like creature slither out of Barb's mouth and across her face.
Will stayed in the Upside Down for a week and had a tendril extending down his throat after being captured by the Monster. A month after returning home, Will coughed up one of the slug-like creatures and washed it down his bathroom sink drain.
The slugs were dark brown-green in color, with bright yellow spots.
