Games : Name of game boy game with bridges

I am searching for a Game Boy game which consisted of the user changing the position of a bridge (which if I remember correctly looked more like a block). There were pathways (looked somehow like pipes?) and there were characters walking on them. When you placed the bridge the character used the bridge instead of following the path straight.

You lost if the character fell (end of the pipe) and you won if you got all characters to the end (I cannot remember if there was just one or more).

I know it was part of a multicart cartridge, and the name may have been in an asiatic language...

I have no more clues and can't find it. Anyone knows this game?
