Settle in and let yourself be carried away by the music of the Shells band in our “Ocean Lounge” puzzle, a colorful and playful creation by Dean MacAdam. The shark, cigar in mouth, is in for a surprise when he discovers his beloved’s engagement ring is missing. Will he notice the blue crab with its thieving claws? That could really spoil the party. The deep-sea diver would agree—if he could.
