...That's a dumb title and I'm not ashamed of it.
So, you ever see a video of someone in a Pom-Pom costume getting harmlessly caught in a door for a few seconds and your brain mutates it into "okay, imagine this, but it's the real Pom-Pom, and the reason they got stuck was because their butt was just simply too big to go through the door?"
...I know, not a normal question, but hey, at least the rear view is pretty cute.
Seems like here, they underestimated the roundness and jiggliness of their big fat rump, and got stuck! Fear not, Pom-Pom! Just do what every pearshaped character on this account does and call the mascot Nameless to give you a quick PUSH! Or just wiggle your way through the door yourself, which they seem to be doing, although fair warning to them, it might give everyone around them a big wobbly view of that big wobbly rear for a few minutes...or hours...On the bright side, doesn't seem like anyone's complaining yet, huh?

In case you wanna.....uhm, I dunno, Discord sticker? Make them fit through other stuff? I dunno, lol, but hey, better to have it.
