What on Earth?

The documentary investigates alien‑like metal monsters that emerge from the ocean, examining their strange appearance and behaviour. It also follows an epic clash between thirty million crabs and a legion of killer ants, portraying the scale of the massive battle.

This is a documentary episode that investigates a series of extraordinary phenomena. It presents itself as a factual programme, focusing on bizarre, seemingly extraterrestrial creatures that have been observed emerging from the ocean. The format follows the conventions of a typical documentary, delivering its material in a straightforward, informative style. The central narrative follows two striking storylines. First, the film examines alien‑like metal monsters that rise from the sea, highlighting their uncanny, metallic appearance and the mystery surrounding their origin. Second, it chronicles an immense confrontation pitting thirty million crabs against an organised army of killer ants, portraying the sheer scale of the clash and the unusual participants involved. Throughout the episode, the documentary supplies visual material and commentary that detail both the oceanic metal beings and the massive crab‑ant battle. By juxtaposing these two extraordinary subjects, the programme offers viewers a glimpse into a world where mechanical‑looking sea monsters and a colossal insect war coexist, underscoring the odd and compelling nature of the events it records.
