My wallet, phone (notebook/enemy intel), headphones.
There's a 100% chance of me dropping my glasses of eagle sight. Depending on the flavor of mountain dew I drank before I died, I would drop different colored potions/meds/ammo/invincibility/charms etc.
White Out(white): Invincibility-re-fills ammo, health, magic, etc., triples it, and gives unlimited health for a short period of time.
Code Red(red): +Attack-gives double of any offensive attack (2x Ammo, 2xMagic, etc.) for a period of time.
Live Wire(orange): +Defense-gives temporary boost of defensive stats (shields/armor) and ups speed.
Voltage(blue): Sp. Attack re-fill-whatever your special attack is, pick this up and you will re-fill the bar/gauge by 25% to 50%.
Regular Mtn Dew(green): +Any Stat-randomly re-fills anything (except Sp. Attack gauge) slightly by 15% to 25%.
You can't tell what I'll drop by looking at me, so you'll have to kill me to see. Even my stronger forms wouldn't have the White Out power-up, so you would be taking a chance with what I would drop all the time.
