The small bears

"The Small Bears" by Gene L. Henderson is a science fiction novella that was likely written in the early 1950s. The narrative unfolds in a mysterious alien landscape, where a crew from Earth investigates a planet that has absorbed previous expeditions. The story delves into themes of alien intelligence and the hidden perils that come with first contact. The plot centers around Dr. Dick Boyette and the crew of the space-cruiser "Assault", who land on a planet that has resulted in the disappearance of numerous ships. As they explore, they encounter small, teddy bear-like aliens that initially appear harmless but are later revealed to possess telepathic abilities capable of manipulating human thoughts. Dr. Boyette discovers that these creatures have led previous crews to their demise by compelling them to jump into a lake of molten rock. Utilizing a truth serum, he learns of the aliens' plan to infiltrate Earth through the guise of pets to incite destructive conflicts. Ultimately, Boyette advocates for an alternative approach, suggesting the introduction of fleas to disrupt the aliens' hypnotic control, proposing a potential avenue for peaceful coexistence rather than annihilation.
