The first thing that the Purple One did in her position as the new CEO of Tumblr Inc was to make the building look and feel like the human website as much as possible. The Purple One sought to recreate Tumblr and all of its content, since it did not exist in the monster's world.
"THERE ARE FIVE SIDES TO TUMBLR. THERE'S THE SOCIAL JUSTICE SIDE, THE FANDOM SIDE, THE ARTISTIC SIDE, THE PORN SIDE, AND THE RETARD SIDE. WE'RE GONNA REWRITE AND RECAPTURE THE BRILLIANCE OF TUMBLR SO THAT THE MONSTERS HAVE SOMETHING NEW TO CHERISH"
The Purple One assigned various monsters to different sections of Tumblr. The tentacle monster was assigned to the porn side, George Sanderson (who was the infamous sock monster) was assigned to the retard side. The Purple One even got the Abominable Snowman to come out of the Himalayas to work on the artistic side since he was so good at making snow cones.
Each section had a station set up where monsters studied all of Tumblr's content, and proceeded to copy it in some way, shape or form. The only difference between the human's Tumblr and the monster's Tumblr was that all the pictures that included humans were replaced by monsters. Even the pictures that featured human arms being cut open by razor blades had to be recreated with monster arms. The Abominable Snowman had a hard time with the art section, since making shitty webcomics about how Star Trek isn't progressive was harder than making snow cones. George Sanderson had an easier time with the retard section, but he was not having fun writing posts about otherkins and ableism, among other things. In fact, the only monster who seemed to be enjoying his job was the tentacle monster, who had lots of fun recreating the mountain of porn Tumblr produced.
Meanwhile, the Purple One was smuggling in her female SJW friends from the human world to help her give these monsters an experience they never asked for. All of the SJWs all looked for the same, except for the hair color, which went wild in every way you could imagine.
