The fact that Eve used to be grumpy is known to everyone who reads the comic; here I guess is my acknowledgment of it. I had the tricky job of drawing "old" Eve without betraying her current shape. "Megatoad" is a reference to yet another competitive eater, throwing back to Eve's first Coney Island visit where she was equally unprepared for the cold.
Coney Island has always been a bittersweet, nostalgic thing, a dream built on dreams. I always end up a little sad by the time I'm there. It represents something to my parents' generation, which is why they brought me. In turn it represents something to me, and that's probably why I went for years as a NYer, and still dream about going. Like all parts of Brooklyn there's been an aggressive injection of developer money to ensure that people never stop dreaming about going, but the facade has its limits. It's still possible to find yourself at a grey and empty beach, with hot dogs and cruddy ketchup dispensers as your only comfort.
The fries line is a little math joke, ho ho, suggesting Eve can chill and eat the fries, or not chill and not eat the fries. Eve is already anxious that her friend group never goes anywhere anymore, an anxiety that is almost a self-fulfilling prophecy.
