The fourth pin in the "Celebrate Today" pin of the month series celebrates "National Unicorn Day" on April 9th. It features the Rainbow Unicorn from Inside Out against a large, glitter purple heart. In a cloud at the bottom of the pin reads "NATIONAL UNICORN DAY" in purple and rainbow letters. The bottom right of the pin has a sculpted calendar page for April 9. This pin was originally supposed to be released at DLR and WDW but was sold through ShopDisney due to COVID-19.
