World 4 - Level 4
Peegue vs The UFOs

There are a lot of things to see and do in Wondertown - but not all parts are accessible at this point. Your task is to rid the town of the UFOs and reach the exit in the lower-left corner. To do so, head to the Powder Keg factory. The generate a new powder keg, move the steel box one step down (purple arrow), then step up three time (yellow arrow) to "prime the pump". Now step down (green arrow) and you'll have a new Barrel. Time your steps carefully with the UFOs, and position a barrel each into the path of as many as you wish/need to destroy.
