For Your Seacrawling Consideration

Is this not the most remarkable, extraordinary adventure location?

* An island owned by some kind of high-level evil rogue/fighter/beastmaster-by-intimidation (Bluto, in the role of Sindbad)
* The average, everyday, boring guard monsters are vultures, war dogs, lions, apes, snakes, and dragons
* The lieutenant-grade guard monsters are an ettin and a roc
* A chest of diamonds, undoubtedly the least of the treasures
* A cave, huge castle, chasm, steep stairway, skull-shaped rock formations, canyon, and active volcano in the vicinity
* Furthermore, the whole shebang sits on the back of a giant whale
* An enchantment renders combat damage into highly implausible ouchie-effects, with several additions to this excellent table.
* Popeye, aided by no useful henchmen to speak of, rolled over the whole place in ten minutes flat.
