1UP

A 1up (can be spelled any number of ways) is an item that appears in almost every Kirby game (and also a common video game term). It gives Kirby an extra life and the player an extra chance to beat the game. If Kirby dies the number of these goes down by one and the player restarts at the section of the stage they died in, if all of these are used up the player recieves a Game Over and must start the whole level over from the begining- Though you won't lose any data that was saved.

Appearence
In early games, they appear simply as a text block that reads "1up", in later games starting with Kirby Super Star they are pictures of Kirby (or whatever character is being played as at the time ex. Meta Knight or King Dedede) with text that reads "1up" written on them.
