Juno's theme in Mega Man Legends is actually Johann Sebastian Bach's, "'Little' Fugue in G minor".

Once the Flutter is fixed up, you can find a special cut scene by going into Roll's room. The scene involves Roll screaming from off screen at Mega Man to get out of her room. It's implied that he accidentally walked in on her while she was changing. After the cut scene ends, Mega Man will do his victory pose.

In the Japanese version of the game, you have more freedom to "abuse animals". You are given total freedom in kicking animals and shooting birds without penalty. This was toned down in the international release, so that you could only kick the dull-colored dogs at the Old City area. Presumably because they are the only animal that can assault you, which would justify a retaliation.
