Not much is known about Hook, the owner and driver of the Peppermint Ferry, AKA Restarting Systems’ personal yacht. Those who have come to contact with him directly have spoken of his various stories as a pirate, sailing the seven seas for treasure. Now he takes a part time job as the driver for a ship that isn't even used 50% of the time. Ah, such is life.

A former circus performer (or at least that’s what she claims), Milk Cap always strives to reach the top of whatever challenge she’s confronting, regardless of difficulty. The shortest and most spirited of the Formation, she’s typically able to break through the despair of a dark situation and cut right to the chase. She also claims to be the Staring Contest Champion, and anybody who says otherwise is a dirty liar who needs to be dealt with 

Despite his struggles with communicating with others, his ability to coordinate and lead a team was what got Portable Charger recruited by the Button Formation. Forced to make a lot of hard calls, Portable is only occasionally able to show his more positive (and sometimes awkward) side, but will ultimately let his emotions get the better of him in the most intense circumstances.

While he came into the Formation with the least experience, Smoke emerged as the heart keeping everybody together. His anxious demeanour eventually gave way to a smug comedic side, occasionally getting him into trouble but ultimately adding a bright side to this once dire mission. Through a series of Smoke Style incidents, he obtained a necessary item to defeat Platinum Button, the Golden Scroll, and helped Paper Clip and Spread regain their memories.
