Did anyone notice that Kirby games seem to be just a modpoge of a bunch of other video games? For example, one of the treasures that you have to get in the Great Cave Offensive of the game Kirby Superstar Ultra is the Triforce. And one of the boss battles of that game is just like a Pokemon battle because it says every action that you or the enemy does and at the end it says stuff like "Your cuteness went up 3! Your softness went up 2!" And there is also a boss that is very similar to a boss from the Mario series.
Its possible to beat a game more than once a day by creating one save, copy it onto different memory cards of whatever and play it the last area before the last boss, then beat the rest of the game on all of the files in a day.
