BCDM: WHENUA's Disc Mark: The Great Disk of Onu-Metru is printed on the Mini CD-ROM included with the European TOA WHENUA set. The disc contains the same program, with some minor differences, that you can download from the KANOKA Club if you have entered a code from a WHENUA KANOKA Card.
The adventure follows TOA WHENUA as he seeks the MATORAN TEHUTTI. Along the way, you are met with the usual challenges: "8-puzzles", a one-of-twenty-seven code, and the usual Pick-Up Sticks. WHENUA's movie is, by far, the most inscrutable of the TOA METRU movies.
