In Episode 1, MOST was starting to form when Eggnog Jr. was talking to Danger Sign about how the latter got sent to space and sincerely apologized. Danger Sign reassured that they were perfectly fine up there and how they were "a huge Nebula Void fan". So they invited Nebula Void to their team. A bit later, Slop, Clay Brick and School ID join MOST. As Danger Sign is contemplating who to bring into MOST, Cheez-It joins because he overhears Danger Sign call them "too extra”..
