90s(?) board game with cards with a castle and mushroom houses on the board

[undergroundp]

I don't really remember what the game was about, it had a pretty big board with a castle drawn on the top with red flags on its towers, a big part of the sky was visible and lower on the board there was a forest with little gems all around and I think 4 mushroom houses of different colors. There was also a place with mines.
The thing is, I don't remember having to use the board ever, there were just some cards. We had to put these cards in something like a little van with wheels and when we moved the van on its wheels, the cards came out.
I hope I'm not confusing and merging two games together with the board and the cards... cause I might be.
Aaand I'm looking for the name of it.
