When this stage was implemented, yellow pixels covered the entire right side of the stage selection screen (it was once completely black), foreshadowing that the Desert series would be rather large at that time.
Also when this stage was implemented, a small island appeared at the bottom right corner of the map. This is currently the location of Beach 3.
On the far right, some small hills can be seen, revealing that the area is mountainous. This area would become the Mountain series of stages.
This is the first stage to introduce enemies with Ice and Freeze weaknesses.
This is also the only stage so far with an enemy that is weak to Freeze.
This is the first stage to copy a previous boss, but with a different attack.
Just like the previous stage, all enemies in this stage have Boxheads.
