Crunchy is a skeleton that Jagex often used for promotional material on the RuneScape website. Crunchy is depicted as a skeletal warrior with a metallic helmet, and was accompanied by a human named Tim. His most famous role was holding the "High Detail" button before RuneScape HD's release. The two also featured on various other pieces of artwork released by Jagex, as well as on the cover of RuneScape - The Official Handbook.
Tim, Crunchy and Eski appeared in the 14th issue of Postbag from the Hedge, which first revealed their names. The letter also revealed that Crunchy is incapable of speech due to his lack of a tongue, lips or lungs. His hands are also prone to falling off, but he is still capable of writing..
Crunchy appears as a bobblehead in the Gower Quest, alongside Tim. Due to being incapable of speech, Tim speaks through him like a ventriloquists dummy. According to Tim, after the Tim and Crunchy bobblehead pets lost the Player Power poll, it was decided that they would be in the quest anyway, but the wrong concept art for them was used by mistake. They are in charge of overseeing the five Environment artists, and they task players with giving them cups of tea before they help rob the Wise Old Man's bank.
- He has a gravestone in the New Varrock graveyard which reads "Crunchy. His bones were sharpened to form Lord Zemouregal's toothpicks."
