Why bubbles call her "mom" by herself?
Native speaker’s answer

Bubbles is reciting the commonly used English expression to wish herself good luck. This expression is a phrase said aloud by a person in the hopes of getting good luck in a game of chance, especially before a dice roll. It is more used like "Mama needs a new pair of shoes." or "Daddy needs a new pair of shoes." You can see these expressions in movies or television as a phrase gamblers use before a dice throw begging for a good result. Bubbles changed the last part of the phrase to "Mr. Bunny's coloring books" from "shoes."
