A music group that performed an amazing cover of Stairway to Heaven A pump so efficient that everyone has one The edible inner core of certain trees

I tread on the edges of myth, A steed of legend, a symbol of purity. I am as elusive as an honest politician.

A tasty leaf we love to see on top every salad and pizza dish we eat

I'm larger than a pond but smaller than a sea. England named an entire district after me.

Hidden in a shell, a treasure lies beneath; silent keeper of pearls, beneath the ocean's breadth. One can me up, or a case closed with a slam; Forty to two hundred eyes, can you guess who I am.
