Mighty Pigs Practice Rink

I noticed it was called Practice Rink when I got it in February this year and I assumed it was always called Practice Rink. I seen videos on YouTube of people buying it when it was first released in January last year and another person buying it in April last year with it still called Mighty Pigs Practice Rink in the store. I think the name must've been changed after the Marge at the Bat update in April last year but before the Black History Month event in February this year.
