{☆SORRY FOR TAKING A GAZZILION YEARS --☆}
Takes place after the 3rd episode of the Trials thing! Srry if u didn't want a plot or smth like thaaatt—
Planet X—,, the unknown planet which was secretly ejected out of the solar system by Jupiter and(?) Saturn. Yet, those two still appear innocent . . . Like said, Jup wouldn't hurt a fly! ...... X was at the sidelines of the solar system. Yep, instead of their empty 'hideout', spying on the other celestial objects and all of their activities(Moon Revolution, Trials, Ganymede and Europa being banished, Etc). HE already wanted to take revenge on THEM. He wanted to take his time, although. Taking note of this,, he still wanted to do something! Soo. . . Why not a silly prank -? He mixed, combined, substances present in dear oh space , or particularly, whatever he could find.
-It took a bit of searching, moving around and all while trying his best to not be caught/found. -Which is why,, of course -- he stayed the farthest from any other celestials(Especially those galilean two moons, or or just the entire "A"/so called Football team of Jup!-), so, they wouldn't his gravity affecting them. Considering he's big. . .
Now, when the planets(Or maybe even moons?) were busy—,, he quickly sneaked in and dumped his pretty potions into each one's atmosphere.

Jupiter was still being paranoid about X still being there or not. While,, Saturn consoled him. The both of them did indeed feel an 'itch' in their 'back', but 'shrugged' it off -- well,, if they could of course as planets.* While Jupiter was being depressed about the topic,, and Saturn behind him comforting him. Saturn noticed the other big spherical gas planet growing... a tail, and ears? — Made of certain gases, blatantly.
-Saturn also noticed the same happening to him, and once his eyes looked around, the same for others too. -Saturn's eyes widened as he immediately informed Jupiter - well, tried :P
Saturn: "U-Uh.. J-Jup-piter-!"
