Where is the piggy bank in He Vivi Village?

Piggy Park is located in the upper right corner of the square, next to the pond. At first, there was no such place. You have to find three or four piglets through the task first, and then a kitten MM wearing a pig hat will come out and talk to you, saying that you can open a pig park. Then the next day, the place next to the pond that was blocked before came out and went in. Yes, there will be divination paper in it.
