Falling In Love Again After Heartbreak Poor Squidward has the worst luck with love
One gal never was seen again after one episode
the other crush was Patrick in disguise and now Plankton in a robo disguise florist gal Petunia.

He'd be better off with someone he knows more who's helped him in prior episodes.
i think this would have been a nice end to the episode where Sandy tends to his wounds. sort of like a Florence nightingale effect end
