A Specialty Unit I designed based on the Bluey episodes Grannies (S1E28), Bus (S2E22) and Granny Mobile (S3E33), the latter of which provided us with the with insight to incorporate Bluey and Bingo's cousin Muffin. While Bluey herself had initially been considered as a driver or passenger, we at the studio felt it may be disillusioning to young fans as Bluey would simultaneously be making her third balloon appearance.
