So in my dream here's how the spell went.

Basically you go underwater with this strange block of ice that glows green, you swim in this underwater ritual thing and grab this yellow sphere thing from a Bill carved into a rock wall and put it in the center of the ritual next to a small block of clay, then shape the clay into a a noticeable shape then carve details into it.
All this MUST has to happen INSIDE the ritual site and at Night on a full moon.

That's all I remember of it. Basically the Turtles because TurtleMer's in it.
Ya...........
I know, well basically I've been working on my story The Princess and Tge Hothead which has the Teenage Mutant Ninja Turtles in it so that may add up to why they were in it.
