I was researching the Red Sea Sharks for this chapter! As well as The Crab with the Golden Claws. That said, a lot of Tintin’'s stories involve escapads on ships, as people travelled by ship in the early 20th century. It was not until much later when passenger air travel was more common, which could be seen in the later Tintin stories such as Tintin in Tibet and Flight 714.
@Chikahiro HOLY CRAP this is excellent. This will be my canon image and depiction of Bluey if I ever do new stories of him after this series.
