Lost Cities Realm...

Now like a lot of us I'm the type that likes to try and get through a game on my own rather than ask for help... but unfortunately, like many of us, I hit that point where I just give up...

I recieved A Hero's Tail for Christmas along with three other versions of Spyro, and I'm pretty new to it... but anyway, I've destroyed the dark Gems and beat the boss of the level, but where do I go from there? To get to the next realm I mean...

I've been to the Cloud Domain as well as the Sunken Ruins, but I found no means of being teleported to another realm in either of them....

Help?

I can not find my way through the sunken ruins. If you can help I will let you know if I can find anything to teleport to another world.
