Cuddles' recent blind date comes with an unexpected twist: her Siamese twin sister is also in the picture and asks him to help find her a date. Rocko intervenes and quickly realizes he’s met his match in the sister, who is sharp-tongued and resentful. To everyone's astonishment, their initial antagonism transforms into an intense romance, while Cuddles discovers that the other sister is much duller than her enticing profile suggested.
