Lup is Extra because she decorated the entirety of the StarBlaster in old polaroids of Taako spanning from when the siblings were barely a month old to the start of cycle 99. Magnus and Merle had to chip in a bunch from their adventures, but nevertheless, there is a detailed timeline spanning from tail to tip of the ship. All through the hallways are the incredible scents of dishes Taako taught Lup to make over the years. She had the whole thing kept secret from her brother, and revealed it as a celebration for his friends and family to show how much they love their own personal celebrity.
