In this episode we return to a recurring theme in the series, which is wishing for more than what we have. This time, Sebastian's the one feeling a little down with the tide. For some reason or the other, he's being pushed around and swept up in crowds more often than usual, and is feeling very small and helpless.
The gang (Ariel, Flounder and Urchin) try to cheer him up by playing Urchin's new board game, but when Urchin suggests that he use Sebastian as one of the board pieces, the crab snaps. He loses his temper and flails around screaming injustice at being treated as nothing more than a tiny little runt, while his friends watch in horror.
That night Urchin and Flounder meet up with Ariel at the palace. Urchin explains that he's exchanged his game for a map leading to a Magical Cave, where he hopes they can find a way to help Sebastian. There, they learn that one of them may enter the cave and gain magic to do all sorts of spells. After Urchin backs out nervously, Ariel volunteers. Ariel, now a sea witch, wishes for Sebastian to become big, but nothing happens. At first.
The next day, Sebastian starts growing... and growing... and growing. At first Sebastian is incredibly happy, and uses his new size to help the merpeople. He gains popularity among Atlanticans, and though the gang are happy for him, they miss being able to just hang out.
Soon enough, Sebastian's size becomes too much. He's become destructive and is overeating. He asks for Ariel to adjust his size a little bit, and when Ariel tries to comply, her magic doesn't work. Sebastian announces that he has to leave Atlantica, but the gang are quick to follow. They return to the Magical Cave, and learn that Ariel's magic will only be replenished during the full moon.
But Sebastian continues to grow, until his head bursts through the surface of the ocean. He is spotted by human whalers, who immediately try to capture him. But it just so happens that there is a full moon out, and Ariel can use her magic. After a few false starts, Ariel manages to save the day, and everything's back to normal — literally.
As for Sebastian, at last he realises that he has wonderful friends, and being small doesn't really matter that much anyway.
On the whole, this story isn't really about Sebastian... It's more about the friendships between Sebastian, Ariel, Flounder and Urchin, and how they truly want each other to be happy.
PS. I also refer to this episode as the one where Sebastian and Ariel act like total teenagers; Sebastian with his temper-tantrum, and Ariel with her girly squealing (over the idea of shopping, and seeing the sea-horse board play piece).
|Urchin:||Are you all right?|
|Sebastian:||All right? All right? If being a squish-squashed beat-up little runt is all right... I'm all right.|
|Ariel:||The last time you sold us a map we got captured by a giant octopus, chained by the Evil Manta, and trapped in a terrible cave-in.|
|Moray Eel:||See what a great time you had?|
|Flounder:||Do you think we should do it, Ariel? Sea witches use magic, you know.|
|Ariel:||You're right, Flounder. But Urchin is right, too. We have to do it. For Sebastian.|
|All three:||For Sebastian.|
|Magic Cave:||I have the power to give you magic beyond your wildest dreams. But first, hoooooow's my breath?|
|Sebastian:||( Talking in his sleep. ) I wanna be... a great big crab. I wanna be... a great big crab.|
|Flounder:||I think he wants to be a great big crab.|
|Ariel:||Does he seem bigger to you?|
|Flounder:||His snoring seems bigger.|
|Sebastian:||( Speaking to a shark. ) The ocean's not big enough for the both us, man. It's barely big enough for me!|
|Sebastian:||I guess I'm just too big to hang around you little guys.|
|Octopus:||When a whale is a little guy, you have a big problem.|
|Ariel:||You can't leave us, Sebastian, 'cause... 'Cause we're going with you. We got you into this, and we'll stick by you.|
|Urchin:||No matter how humongous you are.|
