The bad guy in this episode is named Sta-Lak. He's not named this time, but will make a return appearance (so he apparently survives when his ship crashes at the episode's end) in which he is named.
It is this episode when the bad guy specifically gives Amzot's "riches" as the reason for attacking it. This statement can easily support my theory that the energy rocks are the most valuable resource on the planet.
Also, Zandor specifically calls them energy rocks. In a previous post, I did not consciously remember this and dubbed them energy rocks as if I were thinking up the name myself. Sorry about that.
We learn a little bit more about the Herculoids. Gloop (and presumably Gleep) has super-strength comparable to Igoo and is very heat-resistant. This is demonstrated when Gloop stands RIGHT IN THE EXHAUST OF A SPACE SHIP while temporarily holding the ship down as it attempts to blast off.
Also, it's obvious from this episode that the chattering of Gloop and Gleep is an actual language. I still think all the Herculoids share a low-level telepathic link and that all have reasonably high intelligence, but when Zandor (during his career as a geneticist) created Gloop and Gleep, he was in effect creating a new sentient race.
We don't learn a lot about Amzot. Most of the action takes place in the arid, desert-like area near the Herculoids' home. There is a reference to the White Cliffs and this includes a tar pit that Igoo unceremoniously falls in after dropping from Sta-Lak's ship. I'm placing this specific region on the north end of the desert.
A--Desert (mesas, cliffs, occasional tar pits, occasional
flora including Iron Trees) The north end of the desert area contains the White
Cliffs.
B-Jungle (various flora, including Rubber Vines &
Kona-nuts. Also, ants, grubs & snails)
C-Canopy Trees
1. Dark
River --flows south from
jungle, with a 300-foot high waterfall known as The Bottomless Waterfall
located not far out of the jungle.
2. Monkey-People--strong but shy & unaggressive flying
monkeys. They are semi-sentient, with a very primitive language and loose
tribal structure. They eat plants, insects and small mollusks.
3. Hill area that is home to the Parrot People. They are
avian humanoids with a warlike, aggressive culture that once enslaved the
Monkey People. They are omnivorous & have a sophicticated language and some
technology, allowing them to make clothes and fashion wooden clubs. They are
largely contained to the hill area due to their fear of the Herculoids.
Iron Trees--Large (50 foot or higher) trees that sparsely
populate the desert area. These trees have very deep roots to access
underground water sources. Their name derives from their extremely tough outer
bark, which can withstand violent impacts without showing any damage. Zandor's
shield is made from Iron Tree bark.
Rubber Vines--Thick, pliable vines that grow down from the
limbs of certain tall trees. They anchor themselves in the ground to search for
additional water. Zandor has learned to use the vines as personal catapults to
vacillitate rapid travel through the jungle.
Canopy Trees—Large trees whose thick, tough foliage form a
sort-of ledge half-way up the trunk, with more foliage forming a roof. Zandor
and his family make a home in one of these trees.
Kona Nuts--a tasty fruit found in the jungles of Amzot. In size,
shape and taste, it is nearly identical to Earth's coconut.
