The Summer Party is a event that started on July 15, 2020. The Green Rectangle Sunglasses are available to collect at the Port. All of the active Pirate Island rooms are decorated for the event.
The event was confirmed by RocketSnail on Discord on July 4, 2020. It was originally due to release the week of July 6, but was delayed.
The rooms were designed by Duqo. This marks the first time a community member who is not part of the Box Critters Team has contributed room artwork to the game.
