The Happy Unicorn
Using the compass on the map, go to coordinates (1617,2295). There you will find a couch and a shopping cart with a tv in it. Stand next to the couch and pull out the remote hacking device and face the tv. There will be a floating invisible switch next to the tv. Turn the switch on and the tv will turn on and an 8-bit unicorn will be dancing on the tv with the words “happy unicorn”.
