While there were still the occasional growls and grumbles whenever she did something they considered annoying, since Clarity's visit the machines of Tech Tock hadn't tried to pull off any further pranks on Star. They hadn't apologized, of course, and they often still attempted to raise tension every once in a bit, but no full pranks had been pulled. Except for the usual ones amongst each other. And Bubo had at some point found himself buried inside of a cream pie, further adding to the strange mystery that was how the machines managed to keep using edible items as ammunition for their hijinks when Hay himself couldn't afford much food for the shop.
Anywho, the new pony entering the shop caused a small murmur to spread among the machines as Star greeted her. What they were up to, who could tell, but for now at least they seemed to be remaining relatively quiet. Whether or not this was a good thing, who knows.
Further back into the shop there was what looked like the a dome styled... thingie... Kind of shaped like a turtle shell actually, and from inside there came the occasional loud clangs, bangs and sounds of things scrapping or clattering that Star had most likely had to put up with for a little while now. On top of the dome was a hatch, and soon after Star had spoken the shops motto it swung open to release a large poof of smoke that billowed upwards and left behind a plenty thick trail of smoke that slowly began to thin out. A cuple seconds later, a pair of sooty but green hooves were swung out to grasp the edge of the opening and help Hay poke his head out to excitedly grin around the wrench in his mouth as he looked to see who had come to visit.
"Hi, Yazz!" He called, flailing a hoof in an enthusiastic wave hello as he mispronounced the mare's name, him then spitting out the wrench he held in his teeth and letting it clatter back into the small collection of tools on the floor nearby. He then... well... he didn't necessarily "climb" out of his shell machine thing so much as he did pull himself out and then let himself roll down it, yet he still managed to land on his hooves at the bottom and start trotting over towards Yazz with a spring in his step.
"Haven't seen you in a while. How have you been? Oh," he turned to Star to do a quick introduction between the mares, "Star, this is Yazz. She's Clarity's mom. I met her a little bit ago when I helped out with a party for them. Yazz, this is Star, my new assistant. What can we do for you?" They'd only met once before, but with how Hay sounded when speaking one would think that they were long tome friends. Then again, he sounded like that with everypony, so pretty normal for him.
Bubo, arriving on the scene carrying a pretty heavy looking bag of extra parts and tools out from a back corner of the room, stressed his wings on over to the turtle shell device whatchamajiggy before dropping his cargo onto the growing pile of useful stuff and things growing up next to it, him noticing the new arrival and taking flight in order to fly over and land on his usual spot atop Haywire's head, him then titling his own noggin in curiosity at the newcomer.
"And this is Bubo. Bubo, this is Yazz!" Bubo raised a wing as he gave two cheery chirps to sound a small hello to the new mare.
