Sonic's birthday update is the second in a string of updates coming to Sonic Frontiers throughout the year. New challenges will also be coming to the second update, like the new open zone challenge, which tasks you with running through the islands and beating enemies as fast as you possibly can. Starfall Islands will also be filled with birthday party decorations, like balloons and birthday presents. To keep the celebration going, the update will bring new collectible Koco, who are all wearing party hats, and accessories such as the sunglasses with the starry arch and wings on the side, which are inspired by the title logos from the early Sonic games.
