Of all the things fired, thrown--and even lobbed--at it, Kyurem seems to take it in stride. With seemingly larger Magikarp to fry, it looks like it might even pass over again without much hassle.

That is, until Snor-lord decides to throw literal crap at it.

The Gunk Shot hits its tail first, followed directly by a Draco Meteor straight to the face. There were some things that the giant ice dragon could ignore. It could ignore a lot of things, really. But there were two things it couldn't stand for: Someone throwing putrid... whatever that was at it, and someone else hitting it in its beautiful (to someone) face.

Okay its going to kill everybody here. You had your chance to go quietly into the night. The window's closed now.

Two things happen in quick succession. Letting out a shrill, ear-splitting screech, the pressure of its presence hammers down on them like a ten-ton weight. Those evacuating parties who didn't immediately freeze in fear find themselves beyond the current capacity to concern themselves with personal preservation. They scream, they cry, and many fall to the ground under the dragon's great emotional pressure.

Confusion hits it, but either the dragon shrugs it off, or uses the effects to further fuel its Outrage. Throwing the curry residue back at the party, it uses that momentum to slam into the top of the residential building that they were protecting, the top few stories raining down on the street below.

Is Kyurem having a temper tantrum? Hell yeah it's having a temper tantrum. You threw crap at it. Literally. Crap.
