Who knows!! I'm woefully behind on GBF's Halloween lore, besides the fact that it includes a giant bonfire portal to the land of the dead. But look at this dude!! He's such a perfect, neat little scarecrow and he's good with kids and he likes candy. He's the perfect man. If you wouldn't marry Jack-O here, I'm everely disappointed in you. I especially love his big exagerrated gnarly claws (? Or perhaps they are just pointy gloves! who knows!!) and all the gnarly spikes he's got as accenting.
Even better, since Jack'o'Lantern is available as a summon, you can have him with you year-round! That's right! GBF is so kind to us Halloween-loving fools.
