Shhhhhhhh there's a secret and its out, this is IS@G February Birthday Shell build. IT'S OUT! I wanted to give followers enough time to experiment, with whats going on! You can put walls side by side, then get rid of those walls, can't get rid of walls such as inside the 'A'. You can stack the buildings too! Only use the objects provided as these out my favourites, there is one of everything you can duplicate these to help with your build! Good Luck and have fun! #ISAGfebbuild #fun #challenge
