This video shows you how to get the skull that is hidden in Bad Piggies Flight in the Night Bonus Level 4-VIII. The helmet skull is located above the starting point. Stack the pig and two tnt boxes, on the right most column. Detonate to send the pig through the opening. It should land onto the skull.
If you have a different strategy for completing this level feel free to leave a comment below.
Imagine if the opening to the skull wasn’t there… -.-
Well, the skull would still be possible. Watch the video by Dee Jancter.
