Today, everyone outside the windows has colorful hair. Purple seems to be the most common, so he'll go with that. He's managed alterations to the Beast Brews to do just hair color long ago, so he drinks one (it tastes like artificial grape flavoring), and plans for another for lunch.
And so a small box truck, the kind that would be a food truck on Earth, settles in place at the corner of a park in a grey neighborhood close to the edges of a city in the slightly-less-dense areas. There's a subtle effect about it that should keep 'authorities' from noticing, without something prompting them, at least. And it's definitely bigger on the inside.
Nobody is in the truck's cab, but a short ramp leading to a door in the side folds open near the back, and a light-up sign declares 'The Wandering Store - Premium Groceries & Craft/Hobby Supplies'.
