Mini Forest Rules

Hi! Where can I find full rules for Mini-Forest variation? "Pawns promote to a bishop, dabbaba, alfil, camel, grasshopper or ferz on the 8th rank." -- this is very unclear, we don't know what is dabbaba, for example.
 

I think you need to find how these fairy pieces move, and there is a thread in the 4PC club all about it: https://www.chess.com/clubs/forum/view/the-fairy-pieces-introduction

Thanks a lot! So:
- Pawns promote to a bishop, dabbaba, alfil, camel, grasshopper or ferz on the 8th rank
- All pieces, including king, pawns, bishops (all kind), rooks, can only move on white cells
- If your king captured then opponent got 20 points, and vice verse
- Only "true bishop" isn't limited in number of cells he can pass. Simple bishop and rook can only move via one cell
- Alfil jumps two squares diagonally. Just 1 point. It's like primitive bishop.
- Camel moves 3 squares forward and 1 to the side. It can jump over other pieces. 3 points of exchange. It's like horse.
- Ferz only moves one square diagonally - and why is it worth 1 point of exchange?!
- Grasshopper jumping over other pieces for this 3-point piece is compulsory. When a piece is behind another piece, one square orthogonally/rookways or one square diagonally, with the piece I am talking about in the line of the pin/skewer, and there is no piece in between, then it is attacked.
- Dabbaba: These 1-point pieces jump two squares rookways/orthogonally. But if one of its four directions has a friendly piece on its square that it will land on, it will not move in that direction. If one of its four directions has an enemy piece on it, it must capture it. It can jump over a piece that is next to it, as far as I'm concerned...

Yes, all of that is true.
