Hollow Knight has no shortage of collectibles, many of which are required to get the challenging 112% completion status for the game. One of these collectibles is Grub Jars, which the Knight can break open to free the Grub trapped within. In total, there are 46 Grubs Hollow Knight players can rescue throughout Hallownest.
As you continue to rescue trapped Grubs, you will be gifted more Geo and items from the Grubfather, culminating in the Grubberfly’s Elegy charm. This guide explains how to get every Grub in Hollow Knight with a map of each zone that highlights all Grub locations within, alongside a brief description of all Grub locations to help guide players further.
