|Attack||Deadly on contact|
Red blocks are hazards in Ditto.
Red blocks are square-shaped blocks that are black in colour but have red borders. They vary in size and are most often found clustered together. A smaller red square is in the centre of the block.
Red blocks move horizontally and vertically. They are deadly on contact to both the girl and her reflection. Red blocks are usually found clustered together or in groups. They usually move slowly in one direction and then quickly snap back to the start of their path, meaning that the player must be quick in getting past them before they move too quickly for them to avoid.
