Lance Pitcher is the designer in Poptropica Worldwide Headquarters on Mocktropica.
On Mocktropica, you have to get Lance working at Poptropica HQ again to finish the mountain scene on the island. However, he is working at the cheese factory after having quit his job as a designer. He says that he won't go back to being a designer at Poptropica HQ until the cheese curds stop coming out of the tube in the factory. So, you have to retrieve the climbing axe from the unfinished mountain scene Mt. Funshine on the current summit. After retrieving the axe, you go back to the cheese factory and destroy the cheese curd machine with the axe. After that, Lance will return and finish the mountain scene, also making it a little darker "like my soul" as he says.
