A scene from the UK comics. The rest of the story isn't there (strangely, a different one that uses the same artwork is; that happened now and again.)

But, whatever the situation, here we have Medley making a sand sculpture of Firefly, and now they're gazing adoringly into each other's eyes.

Though it wasn't always this shippy, in the comics they were near inseparable; they often arrived together and worked together if it wasn't a solo story focusing on just one of them. Rescue at Midnight Castle couldn't properly show it; too many characters to give screentime to 'cause we're only getting 'em once — but they tried: the two of them flying and then sliding down the rainbow together is the very first shot, and there's Medley being the one to tell Firefly that the Double Inside-Out Loop was too dangerous (we all know Firefly's response by heart by now: "Danger is my life, Medley!")
