Soon after that in the story arc "Eye of the Beholder", he teams up with and briefly becomes merged with the Sandman into a composite mud monster called Mud-Thing. In this form, Hydro-Man and Sandman had limited intelligence and they did not have the ability to use their shape-shifting abilities as well as before. Although it was composed of the two aforementioned villains, it showed no indication of either villain's persona outside of an infatuation with Sadie Frickett, the current love interest of both villains. Soon after, a theater agent named Travis Rave proposed that Sadie and Mud-Thing be in a show, which Sadie gladly accepted at the prospect of stardom. Unfortunately, when the show proved to be a huge success, Sadie accidentally kissed Travis out of excitement, thereby enraging the jealous Mud-Thing. Mud-Thing ended up going on a rampage and carried Sadie with him to the top a sky-scraper. The creature was eventually defeated with a special gas that dried it out and caused it to crumble apart. Spider-Man managed to save Sadie from her plummet, but she ended up being genuinely upset over the loss of Mud-Thing, knowing that all it had ever done wrong was simply love her. After its defeat by Spider-Man and the police, Sandman and Hydro-Man separated from this form when the police were cleaning up Mud-Thing's remains.
