Booster Bars are Chocolate bars made by the Mr Swirly company. The Bluff Scouts tried to sell them to raise money for new canoes but they were know for tasting like cement so on-one would buy them, When Doug gave Mr Swirly a sample and he learnt his own company made them he takes Doug to his factory to investigate. They discover that wet cement was accidently being poured into the chocolate, Mr Swirly throws out the cement bars and the Bars are produced properly
