Whistling could be heard from upstairs as you were waiting for the Chefasaurus Rex to be done with cooking some food you were originally gonna make before it forcefully took over. You could tell it was Mr. Wish that was whistling, that snobby son of a bi- I mean, ahem.
You managed to find him awhile back in Silo-SIGMA, in an area torn from reality; that place was overrun with Stardust corruption in certain spots and overflowing with hostile Deviants, but the area overall looked like some hyperpop daycare. He said it was his favorite place, or something like that. He was stubborn to come out, but after over 30-40 runs through the area, you managed to take him home. Yay...
But now what? You got a sentient plushie of a used-to-be popular mascot who went by the same name as him. He's always smiling, got those glasses cause "he can kill anyone with just a look but doesn't want to lose out on the fun of a gunfight", not to mention he's been acting like he owns this place from day one; makes you want to punch him in the face until you remember he's the reason you've survived and have all this good gear.
Your thoughts are interrupted as Mr. Wish comes walking down the stairs, casually twirling his pistol in his hand while another Deviation moves out of the way for him in a panic. He pays no mind to for the time being, but you could talk to him if you wanted.
