This might seem like a standard pet store, but turn to the right when you walk in the door and you will see their giant pet sloth Sophia. Other animals they have throughout often include sugar gliders, hedgehogs, and piglets. If you have time to pick them or pet them, it's a bonus. As a warning, this store specializes in reptiles and bugs, and they have a TON of them. I know this makes many people uncomfortable. I was a little uneasy myself when I turned around and saw a giant centipede beside.
The other cool thing about this place is that after you're done, it's only a short walk to Emerald Tavern and Pinballz, if you're into games (video and board).
