@Kajitani-Eizan: True, my suggestion certainly isn't the best one (though "gumbo" doesn't rhyme with "grotto", nor does it sound similar beyond only the first and last letter sounds), but I chose "gratin" because they sound almost exactly the same with grat/grot (the majority of people say those the same exact way), and differ only on the last two/one letters.
However, I like gyozilla's suggestions better anyway. Especially the first one (for risotto). The second one just doesn't seem to flow as well, since being hungry in relation to grottos seems more head-scratch worthy than being tired in relation to caverns. It's not all that far-fetched to become tired when thinking about a place (a cavern in this case) that is traditionally dark.
So in case anybody's keeping track of who likes what, I'm voting for the first suggestion in gyozilla's post...
