Seated Strummer

The Seated Strummer is a treasure that is unlocked when the player scans the K.K. Slider amiibo from the Animal Crossing series. It looks just like the amiibo, and is worth.

Collecting the treasure
After scanning the amiibo on the area selection screen (in any sector), the treasure will appear in one of the Secret Spots of the area. Then, the player has to retrieve the Seated Strummer in that spot.

Trivia

 * Olimar's assumptions in his notes mirror K.K. Slider's portrayal in the Animal Crossing series, as he is seen as a celebrity musician, plays a wide variety of music genres and even takes song requests.
