Bug Blox

Bug Blocks are computer bugs in the shape of a cube that appear as a critical part of the gameplay in Kingdom Hearts coded.

Kingdom Hearts coded
Bug 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 Bug Blocks in order to progress through worlds and the storyline, as well as fix the data worlds.

There are different types of blocks: red ones are normal, those marked with a star contain a prize, and grey blocks cannot be destroyed.
