Barney☑

Barney is a key character in the Roblox horror game Animal Hospital, a boss anomaly, and, according to the lore, a serial killer.

Appearance
Barney looks like an anthropomorphic white rabbit, but there's something unsettling about his appearance from the very beginning:

black slit eyes - as if empty and lifeless;
neat mustache;
brown hat;
checkered trousers;
He always carries a red briefcase (suitcase) with the sign “Do not open”.
In its anomalous form, it becomes truly terrifying: it reveals a huge, fanged mouth, and its eye sockets turn into dark holes with tiny white dots inside.

Personality and behavior
At first, Barney seems almost touchingly polite: he calls the player "dear friend," thanks them for their help, and offers compliments. He knows how to evoke sympathy—for example, asking for a cup of coffee because "he's had a long day." But behind this mask, he's a manipulator: if he's refused, he begins to threaten and guilt-trip them ("You better be careful, I don't like being refused").
