 Diver Dan and Skipper Kipper enter the cabin in which are some of the gold coins. Dan picks up and inspects one of the coins. Outside, Baron Barracuda, with Trigger Fish at his side, closes the door to the cabin; in doing so, he clamps shut Dan s air hose. The Baron locks the door, and steals the key. Laughing wickedly, he leaves. Dan discovers and announces his plight, and asks who could have shut the door on his hose. Skipper declares that it seems like the work of the Baron. Exiting by way of a port-hole, Skipper sees and reports that the door has been locked and that the key is missing. Skipper cries that he will get and return with help as soon as possible. As Dan struggles helplessly, Skipper swims to Minerva s place, finds her there, and reports the problem. Minerva expresses displeasure, and wants to ponder why the Baron would seek to hurt the diver. Skipper pleads that there is no time for musing. Sam the Sawfish comes along. Minerva directs Sam to travel quickly with Skipper and help Dan. The two swim rapidly back to the ship. As Sam begins sawing at the door to unclamp the hose, Skipper tells him to do just that, so that the diver can breathe; Skipper notes that the problem of the lock can be addressed less urgently. Skipper swims to the port-hole, to assure Dan that in another minute Sam will have unclamped the hose. As the hose is unclamped, Dan gratefully thanks Skipper; Skipper insists that thanks should instead be given to Sam; then Skipper hails Sam and directs him to saw around the lock. Sam begins sawing through it. As Dan exits the cabin, he asks how he can ever repay the saving of his life. Skipper waves off the thanks. (Sam seems no longer present.) As Dan begins to leave, Skipper tells him not to forget his gold coins. Skipper collects two or three coins and delivers them to Dan. Dan thanks him for these, and Skipper says that Dan may have all that he wants. Skipper explains that he d like to build an indoor swimming pool in the area now occupied by the coins; Dan is taken aback. Dan says that he must now return to his ship, but will let Skipper know the results of the gold analysis. Skipper walks from the ship, then his ship signals for ascent, which begins.
