Avontuur Classics #1875

In "Spook-kevers," the Robinsons land on a mysterious, cloud-shrouded planet in search of fruit, only to discover floating islands of vegetation drifting above the mist. As they explore in their spacemobiles, they encounter chameleon-like super-amoebas and a primitive human-like race living among the strange, shifting flora.

Marooned on a world of endless water, Scotty Mackay and Jana stumble upon a forgotten civilization that vanished beneath the waves and into the earth. Trapped in a crumbling monorail after an earthquake, they plunge into a vast cavern lit by bioluminescent flora, where they encounter Pa-ark de hermiet—a solitary guardian of a hidden sanctuary known as the garden of peace.
