I do bet it's a hint to getting the old man, though. I betcha... of course, nobody is sure, but why else would they put the old man into gozachi's programming. Just a hunch, but try growing a gozachi with 0 disipline, and getting the cape, and using it many many many times and not breeding him. This is my hypothesis and I shall try it as soon as my hinotamatchi grows up and breeds. Anyone else can try this too, with or without any variations.
(I came to the conclusion of 0 disipline by a certain description in tamagotchi sqaure stating the stubborness of the species)
