The last time a mysterious briefcase arrived on my doorstep, I discovered a
ray gun that accompanied me on an intergalactic rescue mission. So when a new briefcase appeared, I knew it was hero-time!
Packed in pink bubblegum, the weapon-of-choice was revealed:

BubbleGun!

A BubbleGun can shoot bubblegum bubbles that will immobilize all enemies. It is a hybrid ray gun—powered by electricity and air—that has the added advantage of energy-efficiency. The disadvantage is its high cost: 25 cents per dozen bubble shots. Exact change only.

This side shows the BubbleGun's air intake vents and power button:

Would I prefer that the gun was Race-Car Red or Midnight Black? Yes, but I've never surrendered to society's colour stereotypes. Pink or not, I was going to inflict some bubble trouble!
But my sister angrily snatched the gun away and insisted the briefcase was addressed to: "The Bubblegum Bounty-Hunter". She had been saving up quarters for weeks.
Before she left, I asked my bounty-hunter sister to demonstrate the BubbleGun on
video:
She has since flown off to some heroic adventure in space, blasting bubbles at alien fugitives.
Whatever.
I wanted to stay home anyway.

POP!
