Dylan has been at it for days. Even since Dipper had been programmed into their lives, there have been sudden changes in the Dalmatians residence, with many gadgets and home-improved machines installed in their home.

Dylan has become convinced that there's a human responsible for these human-built contraptions and is determined to catch that human. As more man-made machines were built over the past over few days, he's become increasingly paranoid and super vigilant, as his frustration in tracking down the mystery human has driven him to point of insanity. Now sleep deprived and out of his mind, Dylan has become delusional, unable to tell apart from fantasy and reality. However, he is determined to find that human once and for all, as the only word he could form from his mouth is.... "HUMON!!!"

Little did Dylan know however was that all these man-made inventions were built by Dawkins with the courtesy of his Dipper, who's had strong experience with mechanics when he was still a human. And all of it happened right under Dylan's nose.

Based off one of the chapters from an awesome fanfic series "101 + 1" by Agentknow on Archiveofourown.org!
I strongly recommend reading this ongoing fic to see where I got an idea of this pic from. Its plot revolving around a human-turned-dog shrouded with mystery to the Dalmatian family up until the middle of the story provides a thrilling story-driven experience for readers like me!
