==Plot==
Coming to after a nightmare of Eiji taking his Core Medals and being absorbed by his other self, a frightened Ankh takes his paranoia-driven fears on Eiji. By then, Gonzo Shimoda, the new chairman of the neighborhood association arrives to tell Eiji that he has installed several security cameras throughout the neighborhood in response to Ankh sneaking in and out through windows. Furthermore, Shimoda advises Eiji for him and Ankh to leave for the sake of the neighborhood. As Eiji tries to talk Ankh into celebrating Shingo's birthday for Hina's sake, Chiyoko attempts to settle the matter is thwarted by Shimoda's wife Tomoko as he watches the monitor and picks at every minor imperfection in his sight. By then, a Shiro Yummy appears and attacks those Shimoda considers a disgrace to the neighborhood. Kamen Rider OOO confronts the Yummy as it molts into the Shamo Yummy who overwhelms the Kamen Rider with his unorthodox fighting style before Kamen Rider OOO switches to Shagorietar. However, the Shamo Yummy escapes, with Shimoda expressing dismay. By then, Chiyoko takes matters in her own hands by blocking the cameras with Hina's help, resulting with them invoking the Shamo Yummy's wrath as he chases the two girls. Hina uses a ladder to fend their pursuer off before Kamen Rider OOO arrives and assumes Takatorartar. However, learning from the last fight, the Shamo Yummy manages to get the upper hand as Shintaro arrives and transforms into Kamen Rider Birth to help Kamen Rider OOO in double-teaming the monster. But the Yummy is forced to fall back after an indirect attack on Shingo has Kamen Rider OOO assume Putotyra Combo while Erika Satonaka arrives to replenish Kamen Rider Birth's ammo. As Eiji holds Ankh from getting back onto Shingo, with the latter's counterpart now strong enough to absorb Ankh, the Shamo Yummy retreats to the Shimoda residence where his source is revealed to be Tomoko.
