Cave tileset - above and below

[Nanaki_Fan]

Hello,

I am looking for a cave type tileset that allows me to have a unique floor and roof in tight space combination.

Think of it like classic SNES games EVO, EARTHWORM, MARIO ect...  (some pics below)

Ideally what I am looking for is the outline of the "hole in the floor" tileset but without the black bit in the middle to create the edges. Do not be fooled, I will attempt to do this but to save me embarrassment I thought I would ask first!

It is for a commercial game. Ideas below:

Actually it's not so much the tile set but the mapping technique and the use of a parallax image behind that creates that impression.  For example, it would be quite easy to adapt the sort of technique in the map inside the spoiler of this post to do it.

Its close but not what I am after.

i gave it a bash myself and it got the results I needed
