Achub Anifail: Antur Arctig
J. Burchett, S. Vogler, Sian Lewis
Mae arth wen wedi'i darganfod yn farw mewn pentref yn Alasga. Mae'n anarferol iawn i arth wen ddod i blith pobl, ac felly mae rhywbeth mawr o'i le. Unwaith eto, caiff yr efeilliaid Ben a Sara eu gyrru i archwilio'r achos. The body of a white bear is discovered in an Alaskan village, and the twins Ben and Sara are sent to make enquiries into the case. It is obvious that something is not right, as it is unusual for a white bear to come so close to human settlements.
