Rescuing Grubs in Hollow Knight significantly enhances your gameplay experience by providing a variety of rewards that aid in character progression, combat, and exploration. As you save these adorable creatures, you earn increasing amounts of Geo, the game’s currency, which totals around 6,750 upon rescuing all Grubs. Specific milestones yield important rewards such as Mask Shards, which increase your health, and the Grubsong charm, allowing you to generate Geo through damage. Additionally, you will collect crafting materials like Pale Ore, relics such as the Hallownest Seal and King’s Idol, and consumables like the Rancid Egg that ties into quests.

Beyond the tangible rewards, rescuing Grubs adds a layer of emotional depth to the game. The satisfaction of reuniting the Grubs with the Grubfather creates a poignant narrative connection, while obtaining the Collector’s Map assists in tracking down any remaining Grubs. One of the most impactful rewards is the Grubberfly’s Elegy charm, which empowers your combat abilities by enabling strong projectile attacks when at full health. Overall, the process offers both gameplay benefits and an enriched storytelling experience within the beautifully crafted world of Hollow Knight.
