In the animated adult parody film Tarzoon: Shame of the Jungle, Tarzoon encounters the Everything-Devouring Multitudinous Munchers who eat everything in sight. They devour three people, a tree, several hippopotamus, an alligator, an ostrich, a giraffe, and several water buffalo all in a manner of seconds.
In The Return of Hanuman, Maruti is a Big Eater. As a baby, he drank milk from two buffaloes. It only made him look like an elementary school student when he's only three months old. He's not done there yet. He ate all the food supplies from the village where he lives in one night. He also ate bread his friend's mother was making until all of the ingredients were finished.
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. Though he's more muscular than thin. He also took a bite out of a leather belt, although he did that just to spit it out afterwards.
It may not be that evident, but Princess Anna is implied to be one. She sings about wanting to "Stuff some chocolate in [her] face", finishing Hans' sentence with "sandwiches" in their song, and when she blabbers about the wedding ceremony with him, one of the the first details she goes through is that "there'll be soup, roast, and ice cream".
Kung Fu Panda: Similar to Po below, Shifu has been shown putting away large amounts of food in a very short amount of time, most notably during the dumpling fight - 10 or so, each the size of his mouth, within 2 seconds.
One of Beauty's sisters (the redhead who wears a yellow dress) in the second Golden Films version of Beauty and the Beast she's almost always eating sweets in most of her scenes and she brags about eating ten pies and cakes in one sitting, despite this she never seems to put on any weight.
In Yellow Submarine, a denizen of the Sea of Monsters vaccuums up other monsters... it then vaccuums up the submarine...then vaccuums up the background art...then, spotting its own twitching tail, vaccuums itself into nonexistence, leaving the sub slowly spinning in a featureless white void.
Chien Po in Mulan to the point where he is shown eating a bowl of rice randomly in the middle of a brawl, is the only named character to engage in the "order" pun that annoys Chi Fu, and declares he doesn't care about what his potential girlfriends look like or wear—as long as they provide him with food. In the sequel, he ends up withanotherBig Eater, Su.
Pig from Home, for a cat, anyway. How many cats do you know that could scarf down an entire hot dog in a few seconds?
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.
