Amazing Gun Puzzle

This level found near the right side of H Level.

Above, there is a Green Gem and Blue Gem behind a brick wall (requires a bomb or red gun to blow up).

Below, a Box and three Red Cubes and a Blue Laser. The laser will kill any living object (Animals). You can hold a Box above your head to bypass it safely.

Further down, two groups of Blue Cubes that block your access - they can be blasted with a red cube or bypassed in various other ways (eg. blown up with appropriate gun, or scared away with a green cube).

Your rewards are $17 of coins, a Heart and a Bird Locator.
