Made minor edits to some pieces of MrBeast's cave tileset found here: http://opengameart.org/content/m13-cave-platformer-extension

It's a platform meant to hang freely not connected to anything. The middle piece is seamless so you can make it as long as you want. You could also probably re-purpose it as a ramp or something.

Not perfect but I'm no artist and it was good enough for me :D
