Squatch Stack's goods, essays and studio in the chat. Ask "Show me the Squatch Stack shop" and a small shop opens right in the conversation: tees, mugs, hats, stickers and prints with photos, and a Buy button that opens that design's page on the Squatch Stack store, where you pay in your browser (nothing is charged in the chat). Ask for an essay from the Wild Man of the Way, or send the studio a request for something custom: a person reads every one and you get a private token to read the reply. No account, no sign-in.
