These 2 little ghost twins love making music and always do EVERYTHING together. They NEVER do anything alone. They also have A LOT of energy. Also, they LOVE meeting new people. Tanner: He's the older one of the 2, thus being slightly more mature, but not much. Marie: She has a hard time getting the hang of floating around, so she needs her brother's help more than half the time. Even though they're ghosts, they still do normal human things, like eating and sleeping. Why? Dunno.
