Infamous example from The Legend of Zelda: In one of the dungeons, you run into a non-hostile Goriya blocking a door. He's extremely hungry, and will get out of your way once you give him monster chow. The text that appears above him reads "Grumble... Grumble..." and there are no other hints, which caused no end of frustration for players who didn't realize at first that that wasn't dialogue, but rather the noise the monster's stomach was making.
In Final Fantasy X, it happens twice to Tidus in the beginning of the game, after washing ashore near Besaid.
Happens to the player character and partner multiple times in Pokémon Mystery Dungeon: Explorers, as well as once to Bidoof. In Pokémon Super Mystery Dungeon, it's referenced early on, as the partner character mistakes Gabite's voice for the player character's stomach. Later on, it happens during the first encounter with the Expedition Society, starting with Swirlix, with the majority of the other members' (Buizel, Bunnelby, Dedenne, and Archen) following suit in unison. It happens again after the battle with Entei (though it's unclear who's belly is the culprit), and again not long after at the Expedition Society's base (once again to an unclear culprit, though it's implied to be Ampharos'). In the post-game, Mew's stomach growls following a mission.
In New Leaf, this happens regularly to villagers with the Lazy personality type. A random conversation you can have with these kinds of villagers involves them showing off their "stomach clock", which somehow growls the current time of day. When visiting your house, sometimes their stomachs growl as an indication that they need to go back home. And in another random conversation, these villagers may ask you what your favorite kind of pie is. Your answer will cause them to talk about how good that type of pie is- which causes their stomach to growl.
This also occurs to villagers with the Jock personality type in another random conversation. Occasionally they will ask you to look into their eyes and tell them what you think is on their mind. Though the answer options you're given are randomly selected, one of the possible options you can select is "You're hungry". They deny it at first, but their stomach winds up growling right on cue.
And finally, the Smug villagers also have an instance of it. Occasionally when they ask you to fetch some fruit for them, their stomach will growl during the conversation. Unlike the Lazy and Jock villagers (who just have a typical "Growl" onomatopoeia in the text box), the Smug villagers' stomachs actually talk.
