The Secret Cave


Hint:
The Kaboom!s will help you when you release them from their houses if you have prepared in advance for their arrival and you time their release well.

Full Solution:

There are three Kaboom!s which will break through the metal blocks blocking your exit, but you must be ready for them. Move the top metal block left one square and down four. Move the next lower block left one square and down two. Now move to the square immediately below the white timer button. Scan (shift arrow) to the left to look at the bottom house. You will notice the Kaboom!'s eyes showing through the wall in the lower left corner, alternating between being very visible (when it is moving downward) and barely visible (when it is moving left and up). After seeing the very visible eyes, count to two and then walk across the timer button. Immediately move down and stand just to the left of the top metal block. If the timing is right, all three Kaboom!s should come down to your location and be spread out evenly. You can scan upward to double check, if any of the Kaboom!s were destroyed or not released, or if they are unevenly spaced you will need to start again. When the first Kaboom! passes to your right, push the block to trap it, causing an explosion. Immediately move back and down one square and push the metal block right one square to be ready for the next one. Repeat one more time. To get into the houses, you will need to permanently open the white gates. Run across the white timer button up to the round white button and stand on it until the gate closes again. Step off the button and the gate will open. In addition to keys and bonus coins, in each house you will find a clue. These clues give the sequences of moves for each of the three times you go through the transporter. There are two ways to avoid the cannon fire at the end. If you move up across the button that opens the green gates, you can move straight up and usually avoid the fire. Otherwise you can go back and retrieve the single remaining metal block in the first section and use it to block the fire.
