The Broken Ear
In Red Rackham's Treasure, they already know Calculus, who is not hard of hearing. Max Bird follows them, and attacks Tintin underwater and is nearly killed by an octopus. Haddock is the one who meets a shark underwater instead of Tintin. There are natives on the desert island, who bear a strong resemblance to the Arumbayas from "The Broken Ear". Thomson and Thompson are saved from losing their heads when Haddock pretends he is the Idol of Sir Francis Haddock speaking, similar to The Broken Ear. The group is captured by natives, but escape when a volcanic eruption sinks the Island (similar to "Flight 714 to Sydney"). Max Bird meets them at the Marlinspike Hall after they find the treasure, but they overpower him.
