EGG CORRIDOR STORY
Arthur was a great hero!... but he was also a scientist. As a scientist, Arthur took care of a whole bunch of Flying Dragon eggs in an Egg Corridor he built most of himself. His friend Igor worked with him to monitor the eggs too.
When Arthur died Igor went mad and ate the Red Flowers in the corridor. This screwed with his memory and he forgot Arthur died, and he attacked anyone who came into the corridor. For example, Sue, who went to the corridor looking for a means of escape.
When Quote defeated Igor, it turns out that he still tended the eggs. Without anyone to care for them, by the time Quote got back there, they had hatched... into monstrosities. The monstrosities (Zombie Dragons) attacked the place and made it all destroyed. The hatching of the eggs might've been an explosion, causing the robot to remember an explosion, not realizing what was going on. Given that Basil lives under the eggs, this would've killed him. FIN
