The owner of the store arrives and sees Daniel, now transformed into a dog. He sighs. He could guess what had happened. A customer had done something stupid with a magical item and get himself transformed. Yep, this yellow labrador dog was a male. Wouldn't be the first being transformed and he wouldn't be the last either. It did not happen every day or every week, even, but it did occur. So he ignored Daniel's barks, slipped a collar around his neck and attached a leash to it. Daniel tried to bite off the collar and detach the leash but of course he had no opposable thumbs anymore and he couldn't twist out of the collar. He was put in a cage in spite of his barks of protest. He grumbled. Stupid genie! Stupid wish! He could have had plenty of cool things but no, he had to get a genie who had played with words and now he was stuck as a stupid mutt in a stupid magic shop! Daniel lied down and grumbled some more. He wanted to bite that stupid genie but of course she was not there for him to do so. She only mocked him, tricked him and just showed him her cleavage, the stupid slutty bitch! What a lousy genie!
Meanwhile the store owner was pondering what to do with the transformed human he had in a cage. He still possessed human intelligence so he could sell him to a zoo, a circus or a trainer. Or he could transform him further. Or change him back. Or change him into something else. After all, he had to have done something to get transformed, indeed more than probably mischief.
