Timothy ate a bunch of small fish, about sixty of them. After that, he had to put an end to his seafare. He had dared to explore the open ocean, because hunger had encouraged him to do so, but now, it was time to go back home. He didn’t necessarily have to go back to the reef, but he still had to hide somewhere, preferably a spot where there wasn't a dark, bottomless pit below him. He wanted to feel safe, because there was a purchase option that he wanted to buy.
Timothy wanted to, and quite frankly, he had to buy that micro shift ability. The ocean was treacherous and unforgiving, even more so, to the 3.5 meter long, swimming disk that was Timothy. For that matter, he simply had to buy this ability, and alter his size to fit any environment better.
The system encouraged his motives as well as she could. She even gave him the greenlight from her side, regarding the purchasing matter. Apart from that, she also had something else to say.
