Star Squirrels aren't decreasing!

Why aren't the Star Squirrels decreasing!? They just keep increasing. I'm surprised by my own greed! Duplicates are weak, so trades often don't go through, and most of the time they end up on the market. I want to save up Happiness Points~...! For the Sugoroku board game, I somehow managed to get one of each Medal S spot... Just a few more spaces until I complete the 'three times' spots. Sob, I have no luck😂 Alright, let's go play Sugoroku. There's no boost at night, so I can use my dice with peace of mind♪ I also need to water my plants. I'll visit my friends! (๑•̀ㅁ•́๑)✧
