The Queen Grumble is the queen of the Grumbles, being a matured Giggle; a giant, beige-colored creature with 8 tentacles on her head, a smiling mouth with 20 white teeth, a tongue, small pink lips, two large pink eyes with several smaller eyes above and below them, and two lines above her mouth that resemble a nose. She is slightly larger than the standard Grumbles and has a large darkish-pink stretch mark on her forehead, which is how other colony members can tell she is the queen. Her clothes are slightly torn but she is able to live with it.

Giggle is a baby Grumble that loves to hang out with her siblings but secretly Screech because he is a brother of hers.

In its containment chamber, SCP-999—known as “The Tickle Monster”—delights everyone with its uniquely anthropomorphic form. Retaining its bright orange, jelly-like texture, it now resembles a humanoid figure with expressive black eyes, freckles, a playful red bow, and a pinkish-red top. Its friendly smile and endearing presence make it a beacon of positivity in the SCP Foundation. SCP-999’s abilities remain as extraordinary as ever. It exudes an aura of intense happiness, inducing euphoria and uncontrollable laughter in anyone it touches. Prolonged interaction with her but also exposure inside her stomach caused by her swallowing people whole provides lasting relief from psychological conditions like depression and PTSD. Playful by nature, it loves tickling and interacting, amplifying its effects of joy and comfort. More than just a morale booster, SCP-999 neutralizes anger, fear, and hostility, even pacifying hostile anomalies like SCP-682. Its intelligence and adaptability allow it to interact with individuals of all temperaments, making it a universal source of peace. This anthropomorphic SCP-999 combines its playful charm with profound healing powers, earning its place as one of the Foundation’s most beloved and cherished anomalies.
