Dr. Harlow: He is a servant who wears a white lab coat, a blue shirt, a red tie, and black pants, and he wears a blue mask.

Stalker/Ratina: She was a little rat just like Rathew, and they were siblings. Ratina wore a pink bow, but she was a victim of one of Harlow's experiments and became an anomaly—a tall rabbit, almost 2.5 meters tall, with a disturbing smile. However, she remembers her brother and doesn't attack him. She also recognizes her friends and best friends.

Coffee and energy bars: if your sanity starts to deteriorate too much, you need to consume one of these two to avoid going crazy.
Interesting fact: Barney is a serial killer. He kills people, and when he reaches his abnormal form, his eyes turn black with white irises, he grows sharp teeth, and he always carries a knife. However, he's not aggressive towards anyone at the hospital, but if someone from outside dares to threaten any of his friends, Barney is not responsible for his actions and may try to kill. He is hunted by Duck Man, a police officer, but everyone helps Barney hide.
And this takes place in an animal hospital.

Sam: a white anthropomorphic cat with orange and black spots all over his robust body. He has blue eyes and wears some kind of suit because he has a job cleaning up anomalous bodies. He uses it sometimes when the anomaly case is quite advanced, and he cleans them. He uses a weapon with a type of green liquid that helps kill or stabilize anomalies depending on the type. He is kind, cool, loving, protective, loyal, playful, and nervous/shy.

He wears a black cap with "security" written in white. He is kind, quiet, reserved, loving, cool, protective, and loyal. When he gets close to someone, he becomes playful and romantic. :3
