Luke.

A children's hospital that ended up being a hospital for infant deaths? The hospital where Robbie, Luke, Fita, and Clay came had four main doctors, and none of them were quite human. One mouse, Lorna, had white skin, yellow eyes, and blond hair. Two bunny sisters, Willa (purple hair, black eyes, and slightly lilac skin) and Felli (pink hair, black eyes, and slightly pinkish skin). One surgeon, a "human" covered in bandages from head to toe and with powers instead of arms. And then there were the management—people in black suits, and their assistants—mice. The hospital itself was created to kill stupid children, supposedly because all people are sadists. Since Fita and Clay died, Robbie saved Luke from death. True, Luke almost killed Robbie after that, but overall, they developed a good relationship. Robbie and Demm (the slime guy, who used to be human) also have a pretty good relationship. Their only chance is to escape. But will it work?

Now Luke and Robbie moved through the dark corridor only in blind spots, so as not to be seen on the cameras.
