Kirby is perhaps one of the most recognizable video game characters that has ever been created. There is no mistaking the little pink guy for anyone else, and even though most of his games do not deviate from the same formula, they are all deeply loved for the fun platforming that they offer. It may not be the most popular Nintendo series, but most things with Kirby's cute little mug on them sell fairly well and reach a lot of people.
While Kirby's Dream Land 3 is not radically different from the rest of the series as entries such as Canvas Curse are, it was something different at the time. The game took the animal friend mechanic from Kirby's Dream Land 2 and greatly built upon it to make a game that seperated itself from previous entries in the series by rejecting the normal copy ability formula.
