In Beauty and the Beast, Gaston sings about how, when he was a lad, he ate four dozen eggs every morning to help him get large, and now that he's grown, he eats five dozen eggs, so he's roughly the size of a barge.

In the Cosgrove Hall production of The Fool of the World and the Flying Ship, the Glutton is replaced by the Forester's Wife, who - though she is introduced sharing a basket of bread and cakes with the rest of the group - gives no indication of her ability to tuck in. When the Tsar lays out the task that the group must eat an entire feast or be beheaded (long story) she attacks the food with gusto, at one point even forgoing a drinking mug and just drinking wine straight from the spigot. When the Tsar then rolls out a feast table full of desserts, everyone else gets an Oh, Crap! look on their face. The Forester's Wife just licks her lips and goes at it again.
