Strad had a tendency of getting in the quirkiest and weirdest situations. This wasn't just a coincidence though, as he had taken up a well paying job of dungeon crawling. Ancient ruins and strange tunnels had recently been discovered, and the job required able-bodied creatures who could jump, climb, scale and navigate terrain. They never said anything about the tunnel's residences.

The Dungeon slime would often hurl goo at the roo as he tried to explore, making him consistently get stuck in place for them to attack. However, when they found him to be no threat, they decided to probe his body instead. The slimes had spent countless years without contact of vertebrates. They would often go places that made the roo kick, throw and push them away from. So many moved on him at once that he focused less on them, and more on the goo keeping him trapped. Once he broke out, he immediately jumped over the hoard of bio-luminescent slimes, rounding a corner to escape.

However, something had happened. He couldn't form thoughts as well, and his body felt as though it were trapped in a suit of some kind. He looked down to see that the slimes were reforming around him, using him as a vessel for transportation. He tried to get them off, but they had released some sort of hypnosis which put him under their control!
He stayed in place, letting them take over his body and form wings, horns, strange markings and a blade on his right arm. He could see, feel and think, but he couldn't move. They had become one with him. In exchange for his strength and speed, they offered themselves as protection.
The dazed roo began wondering through the dungeon corridors aimlessly, stopping only to let slimes merge onto, or leave him. He crawled up walls, down steep grades, and through strange water that revitalized him. He had become part of the dungeon, until he could escape. That is, if he wanted to.
It was becoming a pleasurable experience to him; being tamed, controlled and used by a force that made him feel like he belonged. The strange energies and nature of the dungeon always kept him well.
