The cross-eyed scare, camera-free: build the face with three sliders, hit five targets, then the invite that is not an invite.
Drag the three sliders until every value sits inside the target band shown above them. Hit GO on a 3-second countdown; score what the face catches when time runs out. Then try the invite. No camera, no face required.
Five expression targets, three seconds each, and the target bands get meaner the further you go. Cross-eye, mouth and close-up are the three dials of the Boo Trend face - the face on screen is a CSS drawing that follows the sliders in real time, so you are building the scare, not performing it. Score the run, pull the Boo index card, and if the number is not the one you wanted, take the invite button and see what the fake friend does at the last second.
