From the designer…. ‘In the summer of 1997, I saw two horse mackerels that had somehow managed to get into the sardine tank at the aquarium. The sight of these two fish being unable to blend in with the shoal of sardines made them seem as if they were on an expedition of self-discovery. What sort of adventures will they have? Imagining this led to the conception of six Cast Puzzles based on oceanographic subjects.’ A happy husband and wife pair of sea horses. Once you have disentangled them, put them back together and make them stand up again.
