One on the only RSCPs that are allowed to roam the RSCP Foundation facility freely is that of RSCP-999 "Your Favorite Pet."
RSCP-999
Description
RSCP-999 ("Your Favorite Pet") is an orange, gelatinous being with the ability to make those who touch its surface happy; over time, this effect has been shown to cure mental trauma in others. 999 is regarded as one of the most benevolent RSCPs under the protection of the RSCP Foundation, even assisting personnel during containment breaches. RSCP-999 also makes slime.
It can cure mental illnesses and make others happy so it seeks Robloxians out to help.
Because RSCP-999 is essentially harmless, it is free to roam the facility at will, but must remain in its pen between 8 and 9PM or during lockdowns. Currently, RSCP-999 is not permitted to leave the facility. Food must be replaced twice daily and the pen kept clean. Personnel may interact with 999 only when on break or not assigned to a task. When 999 becomes bored, it should be played with and spoken to in a calm tone.
There is currently tests as to see if its slime could be made into anti-depressants.
