Dangerous Seed/Stage 7-U

If the sixth boss, whether Shark-Mouth or Monster-Head, was successfully destroyed, the seventh stage takes place in Uranus's orbit. However, two alternate stages are possible if the sixth boss escaped, depending on that boss's identity. If Shark-Mouth escaped, Stage 7 is Pluto's orbit, with Monster-Mouth as the boss. If Monster-Head escaped, Stage 7 is Neptune's orbit, with Ultimate-Tiger as the boss.
