But when he saw a gigantic creature nearby, hunting with its jaws wide open, his legs were shaking so badly he couldn't even stand. [System, what... what is that thing?] [Tyrannosaurus rex, also known as a tyrant lizard, phylum Chordata, class Reptilia, order Saurischia, family Tyrannosauridae.] [Who am I? Where am I? This dream feels so real.] [Host, please stop pretending to be crazy and trying to avoid this. Running away won't solve anything. The contract has been signed. Breach it, and you will be eliminated!] [This episode's mission: Find the missing delicacy. Host, please sample three kinds of dinosaur and identify the tastiest one to recommend to food lovers everywhere.] [System Dad, please let me go! I don't taste good!] Hello, everyone. I'm a food streamer, an occasional wilderness survival streamer, and a guest product promoter. Thank you. Reader's Guide: 1. This story is entirely fictional and set in an imaginary world.
