Bug Block

Blocks, also known as Bugs or Block Corruption, are computer bugs in the shape of a cube that appear as a critical part of the gameplay in Kingdom Hearts coded. Blocks appear in all of the data worlds from Jiminy's Journal; they are a product of the data "bugs" from digitizing the journal. The Data Sora must destroy blocks in order to progress through worlds and the storyline, as well as fix the data worlds. There are different colors of blocks: red ones are normal, those marked with a star contain a prize, and grey blocks cannot be destroyed.
