A deformed, armless changeling child afflicted with mysterious 'Compression Sickness,' sheltered among the town's kids.
Ruby is one of the changeling children Carl shelters in the party's personal space during the bombardment. She is disturbingly malformed — no arms at all, her head sunken in at the top like a deflated soccer ball, walking with a limp and hard to look at — and carries an active debuff, "Compression Sickness," that even Mordecai has never heard of. Watching Toy Story with the others, she flees in terror from the malfunctioning robot Donut, reverting to her blank changeling form; Mordecai gently reassures her.
Her strange, unexplained affliction quietly nags at the party as a clue to the changelings' plight and the flooding tomb.
