Galaxy Contact

Galaxy Contact never had a roll chance, and the Sol's RNG Wiki describes it as removed from the game, only seen used by a developer. The Unobtainable tier applies, there is no creator credit, and the page says it came with the "TBA Update" rather than a numbered one. It surfaced through a leak: it was spotted in the inventory of a player called XC.

The effect shows a glitch on the face, similar to Undefined and Defined, where parts vanish and reappear elsewhere, plus a star above the player with a bright center, blue dust and blue lightning. The idle pose is a laidback float with one hand down and one hand up, like Gargantua's. The star is the same as the ones players collected to get the meteoric egg.

The wiki also offers two guesses, flagged as speculation: it may have been meant for the Dreamspace biome because of the star symbol and glitch, possibly as a replacement for that biome's star aura, though its blue palette does not match Dreamspace's pink. It was once meant for a weather rarity tutorial that was scrapped.
