Yes, it's a working model! The rigging was wonky, but I didn't mind at the time. I don't have access to my VRChat account anymore because I was dumb and deleted the e-mail associated with it before changing it to my new one. I couldn't get VRChat working on Linux and I can't make a new account with a Proton e-mail anyway, so I won't come back to that game in a long time... Don't feel the urge to do that anymore.
This is the mascot of a Polish kids game website called Buliba. I used to play it when I was very young and revisited it with my sister once I got older to make weird jokes about it that were mostly poop-related. Around the height of our weird inside jokes and headcanons about the site, I made this 3D model of Bu. If Buliba switched to a 3D art style in it's early days, It would probably look something like this.
I like Runescape, I love Kirby. Why not combine them together? I actually started rigging this model, but for now I don't have the motivation to finish it. If I ever feel like finishing the rigging, I will provide a download link for this model.
