Specifically, if the frog asks a question or asks the status of the star on the phone, the star can answer the question and add some extra information, so that the star can say more than one sentence.
In addition, the number of words in telephone communication is also affected by the communication time and content. If the telephone conversation is long or the topic discussed is complicated, both parties can have a chance to say a few more words.
Therefore, although the frog is a caller, the star has the opportunity to express his thoughts and opinions in telephone communication, so as to say multiple sentences in the dialogue.
