Hungramps has the appearance of an elderly man with a white mustache and large, white eyebrows above closed eyes. He has a blue tongue and a single prominent tooth in his jaw. His most notable feature is his cone-shaped head with the vertex being the top of his head. He wears a gray kimono, a blue obi, and one-toothed geta sandals with white tabi. He is usually seen with a small drool on the left side of his mouth and his right index finger on the right side.
Bony Spirits Hungramps
In Yo-kai Watch 2, Bony Spirits Hungramps have red obi.
In the anime, Hungramps is an old man. He appears to be lost in thought most of the time. He falls asleep quickly and wakes up shortly after. A running gag in most of his later appearances is his notorious hunger and craving for Yo-kai that one can serve as food, such as Wotchagot, Pride Shrimp, and Spenp. Once he senses the presence of Yo-kai like these, he approaches them and proceeds to eat them. Due to this, he is infamously known as one of the terrifying Yo-kai from the “Eating Clan”.
Hungramps has a seemingly bottomless appetite; thus, when he inspirits someone, that person becomes incredibly ravenous.
Back when Hungramps was alive, he had a granddaughter named Sarah. He loved her very much. When Sarah grew up, she spent less time with him. When Hungramps passed away, he turned into a Yo-kai and waited to see his granddaughter's face. In EP004, he saw Sarah again as a teenager, and she stated that she did want to hang out with him. In EP059, she promised him that she would study hard in order to become a doctor to cure his illness. Seconds before they linked pinkies, Hungramps died. After his death, Sarah continued her studies in order to fulfill that very promise.
Hungramps had a relationship with Tattletell, as shown when she tried to attack him and he offered her a beverage. He also formed a friendship with Grubsnitch, since both Yo-kai have insatiable hunger, which leads to them seeking for food-themed Yo-kai and devouring them. In the White and Red Song Battle, they even form a unit named "Tabemono Gakari" and compete on behalf of the Red team.
Hungramps is infamous among food Yo-kai like Wotchagot and Pride Shrimp for them continuously being victims of his hunger. In EP088, he even turns out to be the culprit of the "food Yo-kai murders", which caused his victims, Wotchagot, Pride Shrimp, and Sumodon to lose their souls. Oddly enough, they seem to forgive him and on top of that they invite him to go out to eat. His hunger does not seem to be limited to normal food Yo-kai, as in EP103 goes to the mall during the New Year in order to catch the recently spawned Spenp and eat them.
There are two versions of Hungramps in Yo-kai Watch 2 with the Bony Spirits version being rarer. The two versions have different skills.
Hungramps can be befriended in the process of completing a story quest. He can also be found in long grass in Uptown Springdale and in long grass, under cars, vending machines and in garbage in Downtown Springdale.
