Ambergris
It turns out that ambergris was a highly coveted substance for centuries. It’s known for its terrible smell – “like a cross between squid and farmyard manure” – but its odor becomes sweeter over time. This substance has been used in expensive perfumes for hundreds of years. Some historians have even gone as far as believing the substance to be edible.
Whale By-Product
Ambergris is a whale by-product. It’s produced in the bile ducts of whales and then it gets excreted. While this sounds pretty nasty, it’s found in nature so rarely that it’s worth a fortune to the right people. Steven and Viola just so happened to stumble across it on a walk on the beach! They couldn’t believe their luck. However, there was a catch.
