I've done a search on this & looked at the online solution but I can only get Qookie 1 key. The metal boxes on the right don't push down. I must be doing something wrong, I just can't see what?
Sonic, have Qookie push the left most box up and over to the left one space, then push the top box left one space. Now push the box you moved first down so that you can squash the kaboom. Push the remaining box in the lava. Now you can get the other keys.
