Guess I'm not a beginner, so these questions sort of go here...
What's Tori hair? Does it add collision space? Examples of Tori hair?

What's an "organic cucumber" and other non-wearable (as far as I know) things do?

Tori hair is self explanatory but you asking for it, It's hair, and it doesn't add collision space it just flop around something like that and the organic cucumber doesn't do anything, It's just a collectors item.

Thank you lol cool floppy Mohawks

Cucumbers are underrated.
I activate mine for luck, like a charm. Hair doesn't add colission, can't be grabbed also.
