Brookhollow Park in Grounded 2 is full of old, stinky food that'll quickly kill you if you're not careful. I'd know, because I died climbing inside a foul trash can in the Signals and Stashes mission. To counter the poisonous stench, you need to find stinkbugs, since these creepy crawlies drop stinkbug parts and gas sacks used in gas-resistant armour and smoothies, respectively.
Annoyingly, stinkbugs put up quite a fight, and even have an AoE gas attack—yes, the exact thing you're hunting them to craft counters to. Before heading out to find a stinkbug, I recommend getting a good ranged weapon, like a bow or staff, so you're not brawling it out in the miasma.
