Sponge



"Sponges! Watch for shrinkage..."

- Agent 1

Sponge Blocks are a level mechanic in Octo Valley of Splatoon.

Description
Sponge Blocks begin as tiny yellow cubes suspended in the air. They rapidly expand when hit by Agent 3's Ink, but shrink when hit by Octarian Ink, making a unique rubbery sound in either case. They have small lights on the corners, which light up in the player's colour when expanding and light up purple when being shrunk by Octarians. They become completely covered with Agent 3's Ink no matter how or where they are shot, making it quite easy to swim on them in squid form. In early missions, they are located over safe surfaces and have few distractions, but later on they are usually over bottomless pits and are surrounded by enemies, requiring careful travel.
