During the oyster scene (in the Disney movie) the R in March flashes. Why?
The old saying is that one should only eat an oyster during the months spelled with an “R”. This, historically, was more preventative medicine than culinary discretion. Summer months bring warmer waters and warmer waters bring spawning oysters and higher bacteria counts. While today there is nothing really wrong with a spawning oyster, they are a bit “creamy” in appearance, texture and flavor (This is quoted from another site on the web). Mother Oyster recognizes that March is a good month for eating oysters and as she doesn’t want her children to be eaten, she advises them to stay with her.
