de Blob 2 ’s story begins in Prisma City, where a general election is about to take place. A mysterious priest named Papa Blanc plans to rig the elections to gain power. He's working for The INKT Corporation, which seeks to drain colour from the city and its inhabitants, uniforming the world in a dull grey. It's up to our hero de Blob and the Colour Underground to restore the city to its vibrant past. De Blob frees the lands one by one, rescuing friends along the way. His mission is to bring colour back to the world, free the population, and stop The INKT Corporation once again.
The gameplay of de Blob 2 has been updated for a more standardised console control scheme. The colour-changing mechanics from the first game return, where de Blob absorbs paint colours into his body. This leads to a platforming and sliding style of gameplay as he paints the world various colours. A competitive multiplayer mode allows up to two Blobs to compete to paint the world quickest, earning points in the process. The game can also be played cooperatively with Pinky, who provides assistance.
