[Chorus: Alphys]
Ooh, we break the laws of attraction
Like you're sent from up above
Got a case of Fishy Love
Ooh, we're like a chemical reaction
Or a code you can't debug
Got a case of Fishy Love

[Post-Chorus: Alphys]
She's always turning to violence
I'm always turning to science
She's so determined she's timeless
And I'm so nervous I'm silent
What if she finds out I'm lying?
What if she sends me home crying?
Why can't I just be kawaii?
And then I'm like
Baby, baby, baby, you're so fine
Mew Mew Kissy Cutie, you'll be mine
Crushing, crushing, crushing on Undyne

[Chorus: Alphys]
Ooh, we break the laws of attraction
Like you're sent from up above
Got a case of Fishy Love
Ooo, we're like an improper fraction
Hope this ship gets safe to shore
Though I'm really quite unsure
[Post-Chorus: Alphys]
She's always turning to violence
I'm always turning to science
She's so determined she's timeless
And I'm so nervous I'm silent
What if she finds out I'm lying?
What if she sends me home crying?
Why can't I just be kawaii?
And then I'm like
Baby, baby, baby, you're so fine
Mew Mew Kissy Cutie, you'll be mine
Crushing, crushing, crushing on Undyne

[Verse: Alphys, Undyne, and Papyrus]
And so you shout it out, and so you shout it out loud
Ooh, we're like a warrior in action
Fit together like a glove
Got a case of Alphy Love
Oh my god how long have you been standing there?
I've been right here the whole time
Okay, now I want to die
Ooh, we break the laws of attraction
A duet will maybe do
I invited Pappy too
Oh, it feels good to be included
Smushed together like a bug
Got a case of Fishy Love
