Pet Potato
Now, our eyesight is questionable, but it looks like this person is dragging a potato sporting a pointed hat on a leash. Why? Because why not? It’s a pet potato! Patty the Potato! Patty the Potato also appears to be a practicing witch or she’s really into Halloween. Maybe the owner wants to simply dip their toes into the uncharted waters of pet ownership.

You know, start small. Start off with an inanimate object i.e. a potato, then work your way up to goldfish. Then a cat. Follow that up with a dog. Perhaps go the Tiger King route and later invest in a pet tiger. Who knows? Maybe this person is a potato whisperer and can communicate with spuds.
