Soaker block

Soaker blocks are a mechanic in Return of the Mammalians.

Description
Soaker blocks are similar to sponges. Visually, they are a white block with an animated pattern of arrows. When attacked, the Soaker block will gradually produce a series of identically sized blocks along a specific path, completely painted in the ink color of whatever activated it. While at least one block from the Soaker block is extended, the main Soaker block will also be completely painted in the same ink colour that it was activated too. The first block will always be in the direction indicated by the arrows.

The blocks will shrink back if the main block is attacked by an enemy or left idle for an extended period of time.
