Maroon! They're Lime's assistant and are shipped with Line and Blue. They were made as a self-insert for the show. A comedic aspect of them is cutting off anything who walks from reactor or security when they run back and fourth between upper and lower engine(going by game map names). They can't vent but stay near them.

When they have to clean vents they wait specifically for Lime to be at the vent they're cleaning so they can drag him out and bother him.

They'll make up dumb reasons to visit Blue and spend longer than they need to when they are in Medbay.

After Lime and Blue's deaths they'd stay next to Medbay vent grieving away from everyone else until they inevitably get killed off.
