This caterpillar/Worm like fella has been in my games for as long, or even longer than Chester had ever been (Back when he was arty antler). His original concept wasn't much; it was just a prop. But it was a prop I liked and had planned to make real back in its first debut. Then, during the remaster of Chester's "2" (technically named project remodel), I had made a model. This is the only photo of the model's existence. Because it's completely lost. He was supposed to crawl on the ceiling and be a "Helper". He also had shoes, red cartoony ones from what I ca recall. More recently, I have started to think of the new Chester's 2, which will not be just Chester and his gang. So I've designed these 2 characters "Boomi" and the "Grubster". These 2 designs are based directly off both teddy, and grubby from the WOW toy brand, Teddy Ruxpin. Grubster is directly based off of grubby, while "Boomi" is based off a bootleg Mexican chuck e cheese restaurant with their mascot having the same name (Boomi). While I was alright with the 2 iterations of "Boomi" I had created, but something about the "Grubster" just didn't sit right with me, it looks a little too weird, or wrong you can also say. Recently he came into my mind for the fact I recently actually GOT a grubby (Christmas), and he started to linger in my head. So, I redesigned him to what I think, is his definitive edition.

His new design (as his past 2 concept) was relatively based off grubby, just not the same iteration. This one is specifically reference from the prototype/concept back when it was supposed to be a puppet show.

For a bit of flair, he has a leaf like color (and would probably have a bit more forest made clothing. His head color is the same as it's been (red) with the orange nose. But going down, the rest of the segments connecting him are different colors. This is concept is specifically based off the toy iteration, though the toy and animatronic look practically identical anyways. He most likely would retain his crawling, but only in more enclosed spots. He would most likely be paired WITH "Boomi Bear" seen in the 2nd image with a bit of the cyberamicness of the first Boomi added into it.

Here is a photo, showing a similar type of plush toy created in the 80s
