Keroro Gunsou Movie 3: Tenkuu Daikessen de Arimasu!

Fuyuki Hinata and the Keroro Platoon explore an abandoned temple in Machu Picchu, Peru. During the search, Keroro triggers a trap, leading them to a hidden chamber containing a large blue crystal on a key-activated stand. Keroro touches the key, activating a machine that causes the temple to shake. The group flees, and during the escape, Keroro loses his Kero Ball. Fuyuki briefly sees a glowing woman before they exit. The girl, now with glowing wings, watches them leave. Meanwhile, something begins to grow inside the crystal.
