Grambles quite shy, and frantic, but never gets very loud in volume. He stutters. Hes a real sweet guy. A passionate pet lover. Runs the Bugsnak ranch. Likes collecting things, knitting sweaters, and giving biiig hugs. Came to Snaktooth looking to become part of a new family. Deeply uncomfortable talking about his past. Fled Snaxburg to keep his Snax safe from Wambus. Swears he sees Lizbert watching him late at night. Gramble is interested in Bugsnax as companions rather than food, opting to raise them as pets to try and train them instead. He has successfully trained a Strabby named Sprout to follow a laser pointer. He is also interested in breeding Snax but has not figured out how they reproduce. He struggles with abandonment issues, telling the Journalist that he joined the expedition in search of a new family, though he refuses to discuss specifics about what happened to his old one. Gramble gets worried easily and tends to jump to conclusions, and is often testy due to his insomnia. He also refuses to consciously eat Bugsnax, unable to understand how the other Grumpuses can do so. This causes serious tension between him and Wambus, who calls him a "weepy little rancher."
