You couldn't fathom what the genie just said, it was so utterly ridiculous to think that you were now just some dog's turd, but it was impossible to ignore as the meaty, rank walls squeezed your new body from all sides. "What?! Why would you make me into shit to get out of the zoo!? Why couldn't you just teleport me onto the walls, not into some dogs rank ass!"
"If you wanted to be on the wall, you should've wished for that, but you wanted out. My magic is very limited beyond the zoo walls, very little I can do for you besides make you into something simple that's not in the zoo until... Later..." The genie states with a mildly frustrated tone. It's like his warnings about his limited wish granting just fell on your deaf ears. Though I guess you were learning that first hand at this point, feeling a film of anal mucus later over your new disgusting shape. You'd shudder if you could, yet the knobby length of turd you now were had no muscles, let alone nerves to move. You were entirely at the hounds bowel mercy.
"Can I at least wish to be free at this point? We're already outside of the zoo so it shouldn't be that bad now, and I really don't want to be dog shit anymore. This is an experience I would rather live without." You mentally shudder, the colon walls caressing your long form at that moment, really helping to define your new log shape.
"I'm afraid not, I will have to recharge myself to cast any more wishes, plus being so far from the zoo has me being drained further. I will have to return and grant your other wish on a different day. So you will probably be stuck like this for a few...days." the tiger yawns, his genie glow now noticeably less distinct, yet you couldn't help but freak out hearing how long you were going to be like this.
"A few days! Nononono! I will not be a German Shepherds shit for a few days!"
"I'm sorry but these are the consequences of such rash wishing. I will return in a few days to grant your next wish. Also, it should be stated the unstable nature of your wishing out here, the effects are wild and anything could happen to you, even though you are just a dogs feces. Don't let anything happen in my absence, lest you risk my magic being permanent. Farewell for now!"
You go to ask about that last comment but with a snap, the genie disappears, leaving behind a cloud of sparkling smoke which the Shepherd doesn't hesitate to release. The anus opening ahead of you, only granting a wisp of light as your chamber rumbled, PHHRRRNNNTTTT! You shivered, now alone and afraid, trapped as a German Shepherds shit, you really hoped nothing would happen to scar you any further.
