How come "has" was used here? and what happens if I replace "has" with "is"?

"Has" can be used with the past participle form of another verb, in this case "won", to create the present perfect tense. The perfect tenses involve more complex time relationships. They build upon simple tenses by combining a verb with "has", "have", or "had". The present perfect tense is used to communicate that the action of the verb was completed prior to the present. In the case of “Mummy pig has won”, has is an auxiliary verb (a helping verb used in the construction of verb forms), and "won" is the past participle. She "won" just before the narrator spoke, just before the present. If we changed "has" to "is" then the sentence becomes grammatically incorrect. "Mummy pig is won" causes a conflict of tenses, "is" is present form and "won" is past tense. Ex: I have played the piano for many years. Ex: She has always loved ballet. Ex: They have cleaned the kitchen. Ex: He has arrived.
