J Key Level

This level is located in Purple Zone Cave, in the E Level.

There is a Yellow Bird you can pick up. Carefully drop down between electric blue cubes (having the bird in hand your descent easier). Use the Grey Gun to fire at the blue cube on the far right to push it on to the button, to disable the red laser.

Continue left/upwards. Use the grey gun to get the electric blue cubes out of your way as needed. Use the grey gun to push a 4-second bomb and Silver Gem into a save room collector if you like. Continue up to a door.

Find a Heart and a cyan dog in the next area. There is a gunman trap if you fire the grey gun at the gunman as it will release the hoard of gunmen above.

Continue upwards past various other enemies. Past the next set of doors is a collection of various gems, the J Key, a heart, 2 blue birds and a box containing a yellow dog.
