These are the character sheets for John, Annie and Stella. They are the family and all work in the alien music industry.
These are a slightly different type of alien. They've got 2 less arms but 2 more fingers than the green aliens. They have flared ankles like their wrists. All the dancers are identical. There will probably be 4 girls and 4 boys.
This is the same arena background but with Stella's set.
