Item Idea: Grub

Pretty much like how Fish used to solely exist as items before being made into Mobs, I had the idea that grubs are a randomly spawning item dropped from mining wooden blocks from logs or trees.

They are not edible but could be fed to more insectivorous Mobs (such as Meerkats when they're added into the game) and could be used for brewing or for upgrading the Fishing Rod to give it a higher chance of catching fish.
