Sorry for being newbie

I just came bacc playing right now, didn't have the chance to continue awhile ago due to work 🥺

But what is this yellow and orange drops on ground mean?

I usually seen this after hitting barrels and boxes or defeating filthoids 

I can't even pick it up huhu

Please enlighten me fellow Phoxhunters ✨ 🥺👉🏻👈🏻
