Sentimental Circus Plushie - Spica With Popo / Medium

i really loved this plushie and it seemed super nice and high quality, the only thing i was confused about is why the hat said master on it? it was the correct size and colour however in the animation spicas hat does say 'spica' on it, and spicas hat saying master on it wouldn't make sense and shappo is the master. this is just confusing but i could be wrong and there could be a reason for her hat saying master, id appreciate someone letting me know
