Sienia Trevellion, of Lark made something so cool for the Arcade. For her gacha there are two rare ice skating rinks that you can win. One is red and green Christmas base(showing) and the other is pink and blue Winter base.
The other base is free (in case you don’t win a base you can still use your skaters) and there are ten animals that you can win including a rare skunk that is tied up in Holiday lights. They are all very low prim but the coolest part is that you rez the base and then you rez the skaters right near the base and they magically attach and skate their little hearts out.
Best of all you can move the base with the skaters on it and it all stays put. I love this item so much!
