In the queue for Flight of the Hippogriff and you'll see Hagrid's Hut where you can hear his faithful boarhound, Fang, howling from inside.

Celebrities
A couple of weeks before your park visit, check the official Universal website to find out which celebs will be visiting/filming. For example, Extra with Mario or Charissa & Tracey Live! are often filmed in front of the Globe Fountain on weekdays. Things like The Voice are filmed onsite and you can try to score tickets online but you will have to meet with their dress code which could be difficult to meet if you are planning on spending the day at the park.
