”…so, that’s basically how the round works and causes ponies to turn into blimps when it detonates. Got it?”  
“Not even in the slightest. But hey, if it works, it works… It’s legal for me to own this thing, right?”  
“Pff, c’mon Linework, if a confectionery baker can own a literal big-bore cannon without anyone batting an eye, I think a piddly little 40mm grenade rifle isn’t anything to worry over. Just, ah, if a two-tailed pegasus ever asks you about it, promise you’ll tell him I gave you one just in case Crash Dive and Pressure Cooker are going at it again and I’m out of town.”  
“Uh… okay, if you say so.”
 
Linework finally tracked down what caused her and Interrobang to end up blimped the other day, a rather apologetic-feeling Night Strike. After admitting why flying an aircraft half-asleep with a loaded grenade rifle in hoof is a bad idea, the pegasus went and raided one of the emergency stashes of Thumpers she keeps at her lot at the Ponyville-adjacent Aerodrome and gifted it to the now-deflated earth pony, along with a round or two. I’m sure this’ll end well for everypony involved!
 
Whoops I’m making another small sequence.
