SCP-527's Addendum

Addendum 527 : 1

SCP-527's bubble gun doesn't originally belong to him. Instead, he bought the gun off of Craigslist. When questioned from who, SCP-527 doesn't remember who he bought it from. Alongside this, the bubble gun has some additionally anomalous abilities aside from the bubbles themselves. The bubble gun does not require any sort of maintenance. It refills and cleans itself with no input from SCP-527. The bubbles produced by the gun are highly durable and cannot be broken by any known methods aside from SCP-1048-E's Area of Effect attack and just letting time pass, as they'll eventually pop on their own. The bubble gun also has a limit on how many bubbles it can fire at once. The limit the gun currently has is 3 regular bubbles and 1 of the special bubbles (bullet, grenade, kinetic, trap) out at the same time. 

Addendum 527 : 2

During my test regarding SCP-527 and SCP-1048-E "Polar," I discovered that Polar's freeze breath went straight through SCP-527's bubble, only affecting the person inside of the bubble. Even after becoming frozen, the bubble didn't pop, and even parts and pieces of the ice cube phased through the bubble but didn't ever pop it. Now, it's known that if you pour bubble soap and stick your finger through a bubble, your finger will phase through the bubble, but SCP-1048-E's ice isn't doused in bubble soap. Also, whenever SCP-527's bubble hits a hard surface, it makes a clinking noise similar to that of metal, which leads me to believe that SCP-527's bubble isn't any ordinary bubble but a special kind of material shaped like a bubble. I also believe that SCP-527's bubble can only be touched by things if the bubble makes direct contact before being touched by anything else, and if anything touches it without it being flown at them, the bubble would phase right through a person. SCP-527 is the only thing that can hit the bubbles, which leads me to my final conclusion of SCP-527's bubble: SCP-527's bubble is a specially made translucent sphere specifically and specially made for SCP-527 that only he can touch and feel.
