Gif: HER SALTY LITTLE MERMAID (Patreon)

HE: "Jeez, this popcorn could really use some salt."

SHE: "Ooh, let me help! I've been studying my witchcraft, and I know a spell to make sea salt out of thin air."

HE: "Come on, babe. We both know your 'witchcraft' is a bunch of bullshit."

SHE: "I can do this!  Watch... Fieri enim iam syreni."

*POOF*

HE: "What the hell? I'm a... a..."

SHE: "Oh, jeez. I was going for sea salt, but I got... sea siren. Oops."

HE: "Oops? I've got tits and a fishtail, and you say oops?"

SHE: "Try to stay calm, honey. I'm sure I can probably sort this out eventually."

HE: "What do you mean, probably? And what do you mean, eventually?"

SHE: "Well, transfiguration is a really complicated thing and it could take some time to undo it. In the meantime, maybe you should stay in the pool for a while so your scales don't dry out."

HE: "What? I don't want to live in the pool!"

SHE: "I'll set it up just right for you, you'll see. I'll keep your water nice and warm, and get you some waterproof furniture and lots of cute bikini tops to wear. My little mermaid will have everything she needs."

HE: "Don't call me your little mermaid!"

SHE: Aw, relax, honey. Life is much better, down where it's wetter, under the sea...

(I wasn't going for a theme, but I seem to have made a bunch of mermaid gifs lately. Hope you folks like sea siren TFs, because there will be more. I guess we can call it Mermaid March!)
