Alien Soldier Unused Boss Lambda Bunny

A scrapped boss, apparently called Lambda Bunny according to a sketch for the box art: You can encounter it in stage 5 (it s just a convenient area to spawn it) by changing ROM offset 0x00036C to 4E 71 4E 71 and 0x0113B4 to 03 EC 00 01 15 B2 00 00 C5 BE. At the end, I show an unused animation of the boss firing its gun.
