Ah, I totally missed the reference.
I… don’t get it. But I also don’t know what “second star on the right” is, so that’s not too surprising
It’s the directions to get to Neverland in the original Peter Pan film by Disney. “Second star on the right, and straight on 'til morning.”
Oh, I see.
I just checked, and the lyrics in French are quite different (which is why it didn’t ring a bell).
The old “it’s 夏休み so let’s go to the beach” episode.
