Paint Tankers (also called Color Tanks or Looters) are a harmless enemy seen only in de Blob. They are the only enemy in the game besides Paintbots that won't openly attack Blob, as they have no combative capabilities.
Background[]
Paint Tankers were deployed during INKT's invasion of Raydia in order to quickly and efficiently store large quantities of paint and transport it to INKT headquarters to be disposed of later. They appear in Hanging Gardens, Chroma City Fun Park, and The Docklands.
Paint Tankers are also seen in Lake Raydia as part of INKT's evacuation of the planet, but they only ever appear in places that Blob cannot reach, as they're only meant to be background objects at this point.
Strategy[]
Paint Tankers are completely defenseless against Blob, so not much strategy is required to defeat one. However, it is worth noting that some of them move pretty quickly, so it might be a little difficult to keep up with one.
To destroy a Paint Tanker, Blob must slam all three of its containers, each one rewarding 10 paint points when slammed. When all three containers have been slammed, Blob's paint points are filled to maximum capacity and he goes into Rainbow Mode for a full minute. During this time, Blob is completely invincible and paints everything random colors (except during missions that require things to be painted a certain color, during which Blob will automatically paint everything the correct color while in Rainbow Mode). His paint points never decrease while Rainbow Mode is active.
