The Occocrans are a race of strange gelatinous blob-like creatures from the marsh planet Gresma that move around on a single slimy "foot", like a snail. They manipulate their organic technology with a cluster of stubby tentacles protruding from both sides of their bodies. Their most obvious physical feature is their unusual heads, which feature a transparent dome filled with coloured orbs. These orbs are responsible for an Occocran's emotions and reasoning, with the currently dominant orb feeding an appendage-like brain in the center. For example, an angry Occocran will feed from their red orb, while an Occocran feeling fearful will feed from their black orb. Their speech has grown around this trait, with many of their expressions involving thought-related terms, like "redthink".
A primer on Occocran speech:
Greenthink = Disgust/Hate
Redthink = Anger/Frustration
Bluethink = Calm/Relaxation
Yellowthink = Joy/Friendliness
Orangethink = Passion/Excitement
Purplethink = Sadness/Shame
Pinkthink = Confusion
Blackthink = Fear
Whitethink = Seriousness
Greythink = Apathy
Thinktanking = Scheming, strategising and planning
Thinkframe = Body
Cortex = Occocran-made organic spacecraft

Occocrans are the first aliens I've drawn that aren't based on any microscopy imagery, rather being a more freeform original creation. They were originally going to be gaseous entities, but that changed early on when I drew their brain orbs.
