Timothy had to teach these goblins a lot of things. If they were to survive in this world independently, they had to learn the four pillars of life, which were: Food, shelter, procreation, and magic.
It would take a lot of time to teach these concepts one by one to over four-hundred goblins, and Timothy didn’t have the patience to teach them, so he went ahead and did the next best thing. He spammed a bunch of information in their brains, using the Brain Tickler ability! He gave them visual examples, in their mind, showing what each pillar meant.
Of course everyone understood that magic was important, so they didn’t pay much attention to that particular pillar of life. Instead, they focused on procreation, which wasn’t surprising at all.
“So I can do more than pee with this thing!?” Many full grown men asked about their penises while they were pondering the new information. “It gets bigger?!”
“It does if you’re lucky,” Tim commented.
