With more than 100 million views, Chica the Spider-Dog is a genuine YouTube celebrity.  And Chica is not just any kind of Spider-Dog; she is a frighteningly fast mutant giant Spider-Dog.

Lurking in the dark, Chica shocks and terrifies people who stumble upon her.  Since she moves with incredible speed, scared humans have no other choice than to run as fast as they can.

The video prank is actually a short horror movie that will leave you both amused and intimidated.  Happy Halloween!
