This early morning, I found a white-colored frog on a leaf in my garden.

I thought it was rare and took a picture of it.

Have you seen such a strange, white-colored frog? (If you're using "such", it is usually used before an adjective. For example, "such a grand hotel" or "such a delicious meal".)

I checked what the white-colored frog was on the Internet.

It was a lucky frog. (Sentences shouldn't start with "and".)
