The Wonderland Board

Hi, I have been reading this forum to answer many questions so far about the wonderland games (thanks to everyone that has helped with hints) but I have a problem that I can't find an answer to. I assume that a kaboom needs to activate the pink button so I can get to the end but the spikes just keep killing them. Any hints pls????????
I have tried searching for an answer so I hope I'm not wasting anyones time by asking it again. On second thoughts I hope that the question has been asked before cause I'd hate to think that the level is that easy that no-one else has had to ask

Read the sign at the spikes.
(At first I thought you meant 'spikey balls'! )

My forehead is red from slapping it!!!!!!! I didn't even click that the box was holding it open at first . My first ever post and it was such an obvious one. Thanks for your time.
P.S. What they say is true, this game does do strange things to your mind lol
