Jyykis

Jyykis, before being slammed into Haggfrys and obliterated.

Jyykis was a mid-sized terrestrial planet. It had an atmosphere very similar to that of Earth's. The people of Jyykis were known as the Floobus, and were a subsentient race of underground dwellers. They feasted on rocks and pebbles. Despite these obvious setbacks, the Floobus grew to become a wealthy and highly successful civilization. Their agricultural skills became a marvel in the Omniverse, earning them visitors from far and wide. Their superior understanding of dirt and soil (which they used as both a food and fertilizer) helped them to grow the largest and most prosperous crops ever seen in Omniversal History.

The Floobus eventually evolved to travel aboveground, and developed spacefaring technologies to conquer the rest of their solar system. Their expansion was quelled when a rogue planet entered the solar system and flung the blossoming world into the neighboring planet of Haggfrys, destroying them both.
