How to get Fizzy pharmacist and other VERY IMPORTANT questions. Please help.

So, as the title says, I kinda have a few problems I need addressing.

1st, I'm semi confused on how to even get all of the new cosmetics and taunts or even custom models people have made into the game. Every time I look it up, I get taken to this helpful link. Which is great! the only problem is that people in the comments are saying that "GCFScape" is out dated. They suggest getting "VPKEedit". And you gotta understand that, for someone who is incredibly not tech savvy, seeing all of that when you go to that site, it's really scary and overwhelming.

I literally have no clue what I'm looking at, or what I'm doing. Sorry to come off as clueless, but sadly that's what I am. I'm more of a visual learner, and up until now, everything for SFM usually had a video to kinda hand hold me through the process. I mean, I even found a video about how to work with the cosmetics once I actually have them.

Which leads me to my next problem: I can't find the damn fizzy pharmacist cosmetic to put in SFM. It's not in the list that I've seen several video's refer to. And that's 'cause that list stopped being updated in 2020 and FP was released 2022.

I'm more than willing to learn anything and take as long as I need to. And I am very aware that I could be asking all this and it might have been answered somewhere I'm just not seeing. But any polite help would be appreciated :')
