15. The escapee

Next to the shell fountain in the Port of Entry is a jailhouse building. It seems that one of the occupants has escaped – two bars are missing and a makeshift escape rope hangs from the window. Listen out for muffled conversations from the other buildings, too.

14. Unusual items for rent

Elsewhere in the Port of Entry, take a look at the sign for “Reliable Rentals” in the stroller rental area, which offers all kinds of bizarre contraptions for lease – including a time machine.

13. Moaning Myrtle

Listen out for Moaning Myrtle in the Wizarding World’s restrooms.

12. Up in the rafters

Look up in the rafters of The Three Broomsticks – you’ll see shadows of house elves and owls moving about.

11. Shrunken heads

On either side of the animatronic hog’s head in the Hog’s Head Pub, you’ll see the shrunken heads used in Harry Potter and the Prisoner of Azkaban. Also behind the bar are bottles of Firewhiskey and Doxy Eggs.

10. Mind your fingers

Don’t miss the snapping, snarling Monster Book of Monsters in Dervish & Banges. Next to the registers, look for a sign detailing the closing procedure for the store.

9. Cuckoo!

At the top of the Owlery, a cuckoo clock-style owl emerges at regular intervals.

8. Replace your missing bones

Tucked away on the shelves of Filch’s Emporium of Confiscated Goods are several bottles of Skele-Gro, the mysterious ointment that enables the re-growth of missing bones.

7. The portable swamp

If you need access to a swamp in a hurry, grab the Portable Swamp from the highest shelves in Zonko’s Joke Shop. Also in the store, as you pass through into Honeydukes, look up to see some Extendable Ears hanging from the ceiling. If it’s quiet enough, you may even hear them whispering.

Note: Zonko's will close when Weasley's Wizard Wheezes opens at Universal Studios Florida's Diagon Alley...so look out for these items in the new store.

6. Untrue stories

The Tomes and Scrolls storefront is packed with the books of fraudulent wizard Gilderoy Lockhart.
