During this chapter, students are introduced to our main characters, Cookies and Cream, with whom students will interact throughout the book. The Next Generation Science Standards (NGSS) scientific practices and crosscutting concepts are integrated throughout our game, so we begin with an immersive tutorial that teaches students how to gather and interpret data, and identify causal mechanisms. This quick introduction leaves students wondering what is wrong with our protagonist, Cookies, who is sleeping more and playing less than his sister Cream.
