Let's get into Josh's current mindset.
You hate yourself, every waking moment is a reminder of what a failure you are. The only escape is alcohol and diving into delusions of fame because people love to hatewatch you. You're too stupid to regulate what you say, and so you gather more and more hate watchers who don't just like to see you say silly things, they legitimately hate you and want you to suffer. You deal with this by repeating mantra's your dad told you during one of his infrequent visits, "They're just jealous, you own them because they constantly think about you", ironic since everytime someone shows cobra behind the scenes, he's preoccupied with the trolls. You severely limit the content you put out to save face, you limit streaming because you're constantly harassed while live. Youtube is only a source of grief and some booze money, but it's also still an emotional crutch to deal with your self hatred. Arguably your lowest moment is getting arrested after your own dad calls the cops after you drunkenly threaten to murder your family and kill yourself on the way to family christmas.
A few months of pain and delusions later you get gifted a bearded dragon by your chum Homeboy Ian. The trolls immediatly begin trying to get it taken away, metro visits multiple times and each time they give a thumbs up "Keep on rockin josh!" This is one of the first times you've legitimately had a win over the trolls, a real tangible win. Metro even commented on how pathetic it was they kept harassing you. Puffers becomes a point of pride and you show him often, ignoring any advice or criticism because you've been vindicated by a source of authority. Time passes, you start to get bored of puffers, the videos of our lizard prisoner decline in favor of horrific pruno concoctions.
One day, when you're going out to have a cig, you think "Hey I'll bring puffers with me, he'd love it out in the chilly november casper wyoming air!" and with him precariously clinging to the front of your outter coat layer's shoulder, you walk out. Immediately, he hops off and scurries into the grass. Your slow boglim reflexes fail to catch him in time, and your extremely poor boglim vision immediatly loses him. You search around Conquistador building B for 2 days, calling your family to help, and finally pleading with your fellow citizens of casper for help finding the now most likely dead dragon.
It doesn't take long for your enemies, the trolls, to find the post and immediatly begin trollign the entire group. They put out false posts saying they found puffers, they even message your sisters saying they found him and it goes so far as to troll your homestep-mom on the phone. It's too much, your carefully and poorly crafted delusion is now utterly broken, your family is now roped into this. How do you react?
I think he just broke down and is being taken care of by his parents, that's why his sister seems to be the one that took over trying to find puff after he had that single post
