“Yeah yeah, I’m hurrying.” You sighed, rolling your eyes while your brothers complained that you needed to hurry in the bathroom. “Just taking a quick bath!” You called and climbed into the tub, your legs feeling weak and numb as you did so. You just checked a minute ago and the water was a fine temperature.

“OH MY GOD!” You shriek, seeing your body change before your eyes. “Sam! Dean!” You scream for them and they bust into the bathroom.

“Y/n! What’s wro- oh my god.” Dean started laughing hysterically and Sam’s jaw just dropped as he tried to fight a smile.

“It’s not funny! What the fuck happened?!” You cursed at them.

“That could be a side affect…” Sam shrugged.


“Wait wait, we have to kill freaking Neptune? Like, King of the sea, Triton, Neptune?” Dean grumbled at Sam around a burger.

Sam grimaced and nodded, looking at you. “Whatcha think, little sis? Can we handle it?”

“Hell yeah, Sammy.” You grinned. “Vengeance for the little mermaid.”

Dean laughed a little, patting your back. “Atta girl.”

You smiled and a bit later you all left the diner, driving to the nearest harbor you could find. Thank god tonight was the full moon and he could be summoned properly.

“This is he weirdest thing we’ve ever done.” You sighed, adjusting the seaweed you wrapped around your head.

“Tell me about it.” Dean looked at you and Sam snapped a picture. “Nice crowns, guys.” He winked and dropped a match into the bowl before dropping it into the ocean.

The water swirled up and he was exactly like you imagined. Merman, beard, trident, and crown. “Yo, Triton!” You called.

“I, am not Triton. He is my lesser counterpart from another sea.” His voice boomed.

“Whatever, anyways, I have an important question.” Dean beckoned him closer.

The figure gravitated towards the three of you and Dean threw the driftwood spear dipped in shark’s blood at him. He dodged it and tossed it back at you. It grazed your leg and you felt a zap before passing out.

You could only assume that everything went fine after that, as you woke up the next morning in a motel room with the boys looking over you.

You hissed in slight pain, shaking your head. “God, what happened?” You groaned.

Sam sighed and frowned slightly, “Neptune knocked you out. Long story short, we killed him and you’re okay.”

“Good. I just… I need to sleep a little longer…” You rolled over and fell back asleep.


“You’re joking. No no no, there is no damn way that Neptune turned me into- into a god damn mermaid!”

Dean snorted, “Cool it, Ariel. We’ll get it fixed.”

“How?! He’s dead and I’m still cursed. How are we going to fix this, Dean?” You frowned.

“Can you breath underwater?” Sam cut in.

“I swear to god…” You started climbing out of the tub.

“Come on, flipper, fight us.” Dean giggled.

You couldn’t help but laugh a little.

“Just… Go find a spell or something and let me be.” You failed at stifling a smile. “I’ll be out in awhile.”

“Peace out, Ursula.” Sam snickered as they left the room.

“Ursula’s an octopus!” You yelled through the door and relaxed into the tub.

“Hm. Maybe this won’t be so bad…”

This is Neptune’s moon, Triton, taken in 1989 by Voyager 2 - the only spacecraft ever to pass it. Triton has fascinating terrain, a thin atmosphere & even evidence for ice volcanoes on this world of peculiar orbit and spin. Ironically, Voyager 2 also confirmed the existence of complete thin rings around Neptune.

Blue Neptune

NASA’s Voyager 2 spacecraft gave humanity its first glimpse of Neptune and its moon Triton in the summer of 1989. This picture of Neptune was produced from the last whole planet images taken through the green and orange filters on the Voyager 2 narrow angle camera.

The picture shows the Great Dark Spot and its companion bright smudge; on the west limb the fast moving bright feature called “Scooter” and the little dark spot are visible. These clouds were seen to persist for as long as Voyager’s cameras could resolve them. North of these, a bright cloud band similar to the south polar streak may be seen.
