Halloween Jj

Jj is for Jack-o-lantern
As you all know, a pumpkin with a face
 carved in it is called a jack-o-lantern

And you may also know that last year a girl
 named Lindsay Lu was dressed up as a jack-o-lantern.

But what do you call a fat jack-o-lantern?

Happy riddle solving in October!
Love, Grandma
