Hallokitty (Scare Your Friends!)
iOS iPhone Entertainment
Scare your family and friends witless this Halloween!
This app disguises itself as "Cute Kitty", an application that shows a video of cute kittens. Encourage your victim to stroke the kittens to hear them purr. Make sure you have the volume turned up (it's even better with headphones). After the kittens have been stroked several times your victim will get a scare followed by a "Happy Halloween" message.
WARNING: It's pretty scary, if your victim is of a nervous disposition we recommend you hold your precious phone while dishing out the scare so they don't drop it and spoil everyone's fun!
