CYM creatures
Based they have no name, and the fact you have no idea who they are or WHY they are there. I'll make a own fanmade info of them. And gave them names... Ummmm... Nothing much for those, just Cyan, Magenta, and Yellow
Species
I'm doing a species thing, cause, based the characters from the "Rob1221universe" may reuse designs from others. I'll count them from "species", which count their physical features. For example, Big, Tall, and Small (from Big Tall Small) have oval eyes which are totally black, and have legs, so their species are beady, square, and legged. While Time Cloner (from Time Clones) have white eyes with black pupils, so its species is peeper, circle, and legged. And stuffs. However, the CYM creatures have a unique design that wasn't reused, which happened only to few characters. So their species is... Bacteria. Cause they look like bacterias.
Origin
Then, with my entire story I made for the Rob1221dev series. I made a story which the characters are like digital, being on a simulation or something. Based it wouldn't make much sense for them to be on those strange places. So, the same thing applies to the CYM creatures. So I guess then it'll make sense why are there.
Goal
Their goal is to push boxes. It doesn't seem that there is any reason for them to push those into targets. But remember, its you who are controlling them.
