what do i need to do next after completing all four block puzzles to move on in the game. one of the guides posted here said that i could turn the switch and get to the lizard room through an opening that i created earlier but I never created an opening and dont know how to create such opening. if it was when i struck the bell, nothing happened when i struck the bell. please help!!!!!!!

you have to hit 2 bells in order to brake the glass, i can;t remeber in what order, but anyway, twat 2 to brake some glass, twat another two to brake some more glass. Sorry aobut being so vague.
