Dash block

The dash block is an obstacle that appears in Sonic Boom: Shattered Crystal. It is a type of block that bars the paths in the levels.

Description
The dash block is a mechanical blue cube with a stubby cone on one end and a disk on the opposite surface.

In gameplay, the dash blocks bar narrow passages that the player often has to use. The only way to destroy a dash block is by hitting them with the Air Dash on the side with the disk; at any other side they are impervious. Glowing yellow and blue arrow icons on the dash blocks indicate where the player has to hit them.

In the Worm Tunnels, there are also dash blocks that obscure the only path through them. The player can boost through those by pressing.
