In order to make money to save the beavers being endangered, Timmy and Ivan plans on helping the school with its funds by having a car wash. Little did they know, Vicky was eavesdropping, and plans on taking the money for herself.
It starts off with Timmy and Ivan poofing back from time and finished their essay on the Declaration of Independence. Later that day, they went to school seeing Trixie overworked. She explained that beavers are starting to become an endangered species, and she's been told by Principal Waxelplax that the school should raise their funds by helping the beavers from becoming extinct. Ivan suggested a carwash would solve the problem. As they were making money for the car wash, Timantha went to the library to take a little break, until she met Sanjay and the two of them quickly began a relationship. Unbeknownst to Timmy and the gang, Vicky plans on stealing the money and frame Timmy and friends to make them pin the blame on each other. Much to Vicky's luck, the fairies saw the whole plot and explained everything to their godchildren. Vicky got busted and got blasted out of the school by Ivan with a water hose. The money was saved and the beavers are no longer endangered.
