 | Hot New Assignment | Hi Candyman! You’re probably wondering: who’s Candyman? It’s you. For reasons that will become clear as I continue to say words, to you. Remember when I assigned your team to work on the cheeky little candy flavors with supernatural properties? Candy! Of all things. I feel like I’m six years old. You’ve probably noticed that sour has seeped into the ecosystem around here. Well, I say we might as well embrace it! We want you to infuse bugs with candy power. We need to know just how super charged a bug can get. It’s obvious 2 and 2 make 4 type research. I don’t need to explain why we’re supercharging bugs with candy powers. You get it. I’ll let you sync up with Pumpkin, a human being, at the O.G.R.R. labs. You should be working together on this. I genuinely believe we can make bugs even more terrifying! Much love, Sloane. | Key Items | |
