The Siam-Neko Yummy (シャムネコヤミー Shamuneko Yamī) is a female Siamese Cat Yummy, with scalpel-like claws and Cell Medal-like objects hanging from her body, created by Kazari after he uses a Cell Medal on a female doctor named Kei Tamura, a genius surgeon who feels the director of the hospital, her father, is holding her back due to her pride and lack of fear for the patients' well being.
As a result, the Yummy uses Tamura to perform unauthorized surgeries by herself, giving her father a heart attack in the process. Eventually getting Tamura out of the hospital, Kamen Rider OOO fights the Siam-Neko Yummy, almost destroying her as Sagohzo Combo before the Yummy retreats back into Tamura and escapes. By the time Eiji finds her, Tamura is consumed by the Siam-Neko Yummy as he uses Takatoratar to free her. As Tamura manages to discard her pride to save her father, the Siam-Neko Yummy is destroyed by Kamen Rider OOO using the OOO Bash on her.
