Shy Guy!
A few minutes ago, i was floating around the sandbox, and i found a building just above cloud level, with a number of people in. I, (being my nosey self), decided to go in and take a look. What i saw made be laugh straight away :D Look at the picture, it's a load of people with Shy Guys avatars, and i was automatically given a group invite and a Shy Guy av. Keep a look out for them!
