I shall, indeed.
I will let you know two things that I discovered that hasn't been mentioned so far:
First, the silver budgie does not appear to have their own taunt, instead turning into a blue budgie to do it. Just to be sure, I tested with a bunch of other animations, as well as the green budgie, and this seems to be the only case where this happens.
Second, there is a weird bug with Vesper's trident. I'm not entirely sure what is happening, but dropping the sword to pick up the trident results in the trident sprite remaining on screen, but now behind and seemingly attached to the sword (it disappears upon picking up the sword, which gives the sword as normal). I only got this to consistently happen as a budgie. Additionally, while holding the trident, picking up Skylar's khopesh results in the khopesh sprite reappearing with the trident sprite behind and attached to it. Again, picking it up gives the trident as normal. For this, I was only able to get it consistently as Vesper.
EDIT: Turns out, the sprite bug that keeps happening with the trident happens to both the trident and the khopesh. I've also started getting it with every character. Not sure why it is happening, but I have a suspicion. I've noticed that, when you pick up a weapon, your previous weapon spawns slightly above your character. It can get stuck in a wall or ceiling, making me wonder if that's what's causing this.
