Doll with Orange Dress is a doll that only appears in Blue's Big Holiday.
In Toyland, the doll was crying and thought nobody wants her as a present, because she is different. The reason that the doll was different was because her dress is orange instead of green. Steve compliments the doll saying that it is unique and thought maybe Orange Kitten would like a doll in a orange dress as a present. Steve gets out a holiday bag and the doll jumps into it.
Orange thanked Steve and Blue for the gift.
