Soft

Bonus points if the person drinking the waste started out small, a mix up at the factory where instead of soda it was waste that got into the soda cans. Just so happens it was bought in bulk because it's addictive, and they bought a years worth thats finished off in hours. Cut to a security guard shining their light onto a 'monster' in the factory gulping down barrels of the stuff until they're big enough to drink from a giant mixing vat. Once the 'sugar' fix is sated, hunger follows, and they're just as ravenous for buildings as they were for soda.

It's a lot like Little Shop of Horrors, made to feed some entity that eats constantly and grows just as quickly to the point its hunger is unstoppable.

Sorority Queen Jenna having a blast during Rush Week as she weeds out potential candidates one by one to the point there are none left. Even goes so far as to eat her own House entirely as she feels they dont live up to her standard. She then moves on to other Houses on campus, even picking up an entire house as she eats through the entire Fraternity/Sorority Row. The next morning, she wakes up having slept on the inner quad of the school, crushing what's left of the school after having devoured the library and cafeteria before sleeping it off.

Always been a fan of Giants destorying houses, heavy things being torn like paper as show of power. Warlock Giantess absolutely pulling off a a whole 'I always loved dollhouses growing up.' when going after some one who she's interrogating, ripping off walls to find him and taunting them to 'Come out and Play!' while having a sinister laugh, put the fear of what she's could do if they don't cooperate. 'I want to play a gane.' her voice sweet, but holding them with very much a threat of violence. Paladin boy just goes on a rampage having skipped a meal trying to control his hunger, ends up lifting the roof of some place and just feasts until he's done. Maybe a few other buildings along the way cause the hunger is strong and needs to be sated.

Also big fan of Preds that are big, and uncaring of how much space they can take up. They could be in an elevator and not even realize someone is squashed between them and the wall. Office Pred Managers squeezing into cubicles to talk to their employees, but more focused on reviewing their numbers as the squirm under their bellies. Preds at nice restaurants as their expanding bodies smother other patrons as they feast. Preds eating one building but one hip check and the adjacent building begins to crumble. Oblivious or intentional, love that concept.

Life coach hired by fed up parents of an adult gamer basement blob. No one told them that this job is with someone literally ten times their size in every way. And no one told them about the other people sent to talk some sense into em, ending up lost in food delivery orders and folds

Werewolf hopeful to hear from their partner that the mega packs of steak from the grocery store have been enough to satiate them during transformations

The local college teams were going head to head on the field, now they're scrambling over eachother trying to scramble out of the ever rising stomach fluids of some:

Ya know how Warioware games have a visual difference for each 3 difficulty levels?
