This story is about Snake King's descendants teaming up with animal protection experts to fight against a black market snake hunting gang bought by real estate developers on Snake King Island.
Skull Island is the name most often used to describe a fictional island that first appeared in the 1933 film King Kong and later appearing in its sequels, the three remakes, and any other King Kong-based media. It is the home of the eponymous King Kong and several other species of creatures, mostly prehistoric and in some cases species that should have been extinct long before the rise of mammalian creatures, along with a primitive society of humans.
