The Wonderland Board

The yellow buttons don't seem to do anything, and full bridges to the exit points don't appear. Is there some secret purpose of the buttons that I can use or is this level impossible?

Same question! There's a sort of thud when you step on one of the buttons, as though something is trying to move but can't. Maybe you have to use a stinker to press both buttons at the same time while some of the bridge tiles are down.

Again I'll say...it's not fun if you can't see the puzzle.

I tried having 2 stinkers on the buttons, alternating buttons, and doing all sorts of things! I have absolutely no clue.

Hint:

The button operate something at the very bottom (south end) of the level.

Aha! Of course, thanks Patrick.

Thanks, Patrick! I would never have guessed that.
