One fine day on Earth, you thought, why not invite your friend/matespirit to the store? Equius knows almost nothing about humans, he's a troll. He lives with you in your house, not understanding how to sleep in a human bed and how to wash in a human shower... Well, you went to the mall and went into the store. There were a lot of people... but you need to buy food, buy personal hygiene items for yourself and Equius, and maybe buy him something as a gift (for example, something for building robots)
