It’s possible to once again obtain a background showing the Penguin Band in the earlier years! You don’t need to meet them in order to receive this – all you need to do is press E and T on your keyboard (to perform the toot emote). If you don’t already have the background, you’ll then be offered it!
I should also note that the Penguin Band are visiting with a more modern background, which is new. In order to obtain that one, you will need to meet them! They’ve already begun visiting the island, but they’ll be making plenty more visits throughout the Music Jam.
For the best chance of meeting them, I’d recommend checking the Penguin Band Tracker here.
