Gold-obsessed trumped up thief Goldbug has managed, with the unwitting help of the Hulk, to finally accomplish his goal, and find El Dorado!!
Auric Goldfinger is spinning in his grave, dude.
PRO-TIP: why not just take some of the gold, and leave the rest behind in the hidden city? Doofus...
From Incredible Hulk #241 (1979)
