Fat Grub is an Item that can be found within common locations, including choice enemy Camps, given by Spouses, and rarely as a reward from Seasonal Festivals. Upon being picked up, tilling Soil will have a chance to give Fertilizer and seeds. This chance is applied to all forms of tilling, including breaking open Crust, basic tilling, or tilling Compact Soil with the Golden Hoe.
Compared to other Items, Fat Grub is one of the few that add extra benefits to tilling Soil, with Burrowed Butterfly and Helpful Worm being some of the few other Items capable of doing the same. However, unlike Fat Grub, both of these Items are centered more around defense and do not directly assist with gathering loot. Because of Fat Grub's ability of rewarding seeds and Fertilizer whenever tiles are tilled it is more oriented with resource collection as opposed to defense. This can prove more beneficial overall if the player is in a place where they do not as much help defending as they do amassing seeds or Fertilizer. As such, when given the option between Fat Grub and either one of these other two Items the player will need to base their decision on their current situation in their run.
