This story is magical realism for obvious reasons. First of all, a boy can't become that fat that quickly, especially when taking into account the diets that he went on in order to stop it. In addition, the author goes into quite some detail and reveals that he is in fact physically transforming into an actual meat turnover which is impossible. The fictional elements work to develop the meaning of this magical realism portrayed throughout the story, and they do so with the help of a realistic setting, impossible events, and authorial reticence. The man vs self plot helps to establish his struggles with himself being so fat, which in turn leads to him giving up and actually becoming a meat turnover. That probably wouldn't have happened if he wasn't having so many internal conflicts. This works with impossible events, as he wouldn't be able to physically turn into a meat turnover, but also he wouldn't have been able to be so fat so quickly, thus the magical realism is being developed. In addition, the dynamic characterization allows for the reader to have a better understanding on the extent that Oscar has fallen, and elaborates on the already pretty magical story. This dynamic characterization works together with authorial reticence in order to leave the readers questioning whether he would actually eat/kill his mother or not, as that is how far gone he is from actual sanity. Lastly, the entire story happens within a realistic setting, cementing this story as magical realist. Thus, the fictional elements described were instrumental in making this story magical realist.
