Chef Pisghetti wants to surprise Netti with a bicycle ride around Endless Park for her birthday. The only problem is, he doesn't know how to ride a bike. Lucky for him, George is an expert!

George is an excellent instructor! But while practicing some of the basics in the park, Chef takes a wrong turn and finds himself hurtling downhill on a runaway bike, headed straight for the Museum. George suddenly remembers that he forgot to show Chef the fourth and final lesson... brake!!

With a little help from Allie and Bill, and a LOT of paint, George gets to work transforming his house into The Man with the... Uh oh! Where will George find a BIG Yellow Hat?!
