To reject the notion of body shaming, she calls herself Fat Allison. She works at Mountain Viewtopia General (the Poop Hospital) and was present during the emergeance of Poopmueller in the hospital's early days.

There is next to nothing that Fat Allison does not already know. She knows everything there is to know about poop. She works in the healthcare industry. She sometimes has a ironic sense of humor.

Fat Allison is partial to getting other people's opinions before forming her own, prefers a good dramatic film, and favors burying her nose in autobiographical material a bit more than her other options. She dislikes working out at the gym, being forced to hear the irritating sounds of country music, and bothering to read books about economics and investments. Fat Allison loves reading passages from Angels & Demons, playing LEGO Harry Potter: Years 5-7, and watching the next episode of North & South like no other.

No nurse at MVT General has earned Fat Allison's level of respect. In the field of poop science, she's arguably as capable as any doctor in the hospital and no one has a greater talent for the comfortable insertion of rectal devices. It's no surprise she's the most-requested healthcare professional in Mountain Viewtopia (at least where butts are concerned).
