Posts of Umamusume's Oguri Cap being a gluttonous monster. Usually this involves her eating prodigiously large quantities of food (even by horsegirl standards). Oguri is often drawn with a bloated belly right after or during the process. Frequently also drawn as a background gag with other events happening in the foreground, like in the Umamusume anime.
Similar to Akagi from Kancolle, this gag is sometimes extended to eating things that are not food (e.g. post #4495566), or stealing and/or eating other people's food (e.g. post #4348429).
So far she hasn't started eating people yet... though post #4591311 comes dangerously close. She DID!
Avoid automatically adding examples of Oguri merely eating food, even if she is doing so ravenously. It has to be gluttonous in some capacity (depicted or implied) to count. Preferably funny too.
The real-life Oguri Cap (the racehorse) was also a noted glutton, sometimes eating an entire day's allotment of hay in one sitting... before proceeding to vacuum up all the bedding in his stall. Then moving onto weeds. And probably also eating a lot of things along the way that shouldn't be eaten.
