In Castle of Dreams/Finding the Gears (Aqua, Brian and Stewie's Story)

Yen Sid: The Great battle with Xehanort is almost upon us. As you know, we must action to keep the seven pure lights safe, and thus we must hasten to assemble the 7 guardians of Light. It is time to return to our world the eight Keyblades Wielder we lost over a decade ago. Ventus, Spyro, Pop Fizz, Terra, Eruptor, Aqua, Stealth Elf and Jet-Vac. Must be saved from their sad end for they have more to achieve. Following their first battle of Skeleton King, Ventus and Spyro's Heart refused to awaken, and so Aqua and her friends found a safe location to conceal them. But when they set off in search of their other friends, Terra, they fell to the place from which there is no return without outside help.
