Favorite Details, Easter Eggs, or Glitches in Ratchet and Clank (2002)?

Hi!! I'm planning on playing through the original R&C soon on my YouTube channel as part of a heartfelt sort of "this is my childhood!" type of love letter to celebrate 100 subscribers. I'm definitely going to be going ALL sorts of wild on every lovable tidbit that I can - stuff like the way the weapons animate when you switch, the unique weapon acquisition animations that we sorta lost later in the series, little bugs like lag-jumps and Zombie Ratchet, the Dan easter eggs - that sort of stuff.

I'm running all of this stuff off of pure nostalgia and while yes, I could search the web for like, a comprehensive list of these sorts of things, I kind of feel like it's more fun and more sincere to operate off of my foggy memory AND things that other fans of the game *personally* hold dear. It's been one of my all-time favorites for over two decades now, and I'm sure it holds as big of a part of many others' hearts out there, too.

So please! If you remember any little thing that you were personally fond of, I'd really love to hear about it. <3
