Anyone remember the 70s TV show "LAND OF THE LOST?"
Most people I talk to seem to recall the lame Chaka monkeyboy when I bring up LOTL. Not me, man. Me, I think of the freaky SLEESTAKS!! They were these creepy reptilian/insectoid dudes running around in caves chasing the Marshall family with crossbows!! They made this hissssing-like noise that made your skin crawl. I don't remember much else, besides that they lived in an underground city, hated the light, and would coccoon themselves into hibernation near a lava pool.
I think I dug them primarily because they reminded me of the Creature of the Black Lagoon, which I saw at a very very young age and obviously made a huge impact on my life.
Oh yeah, they were also afraid of "Big Alice", the stop motion TRex. Awesome.
