Receive 50 Pico Props

GET: 150 gummies

I'd say that the best way to get this star is to stay in a crowded public place. If your pico appearance won't get you props, like peach bi boy, prop as many picos as you can. Many of them will likely prop you back.

 Perhaps doing an action with a cute pico will help...

You may have to change locations a few times, but it shouldn't be long before Star GET!
