Bugs and grubs adds in 3 different bugs you can collect from holding right-click on grass with a bug net, adding a potential food source you can obtain with ease. Each of the bugs can be pestled into a few different items, most notably the bug mush and bug brew, with the former providing a lesser immunity against poison, slowness, and weakness, and the latter providing the player with a greater immunity protecting against all harmful effects momentarily, and giving certain effects for a duration dependent on how many of a specific bug type are put into the recipe.
