Apple

Apples are the main collectible item in Slime-san. They are used to purchase items in stores such as additional playstyles, backgrounds, and clothes for both Slime-san and his bird. Apples can be used to pay to unlock later levels, but doing so prevents the game from being completed 100% as purchasing all other items require all of the apples. Four apples can be found in each of the 100 levels of the original campaign, for a total of 400 apples.
