Seen any ghostly bonuses lately?

Dear Diary,

Finding the eerie picture was easy. Spotting all the ghosts? Not so much. If you can do it successfully though, I’ll give you access to this bone-chilling bonus. It’s a big one (if I do say so myself). Scary good, in fact.

So spot the phantoms, complete the code and claim your bonus. Oh… and Happy Halloween from Australia’s creepiest talking koala!
