Tino the artistic mouse is trying to paint a picture of Duggee but cannot get it right, which infuriates him no end. As he tells the Squirrels: seeking perfection is his whole philosophy! The squirrels don't know what that is, so Duggee explains: a philosophy is a set of rules that you live by. But the rules exist in your head – it's about how you think, not just what you think about.The Squirrels look to questions asked by famous philosophers of the past and some more familiar friends for inspiration, and soon join in with their own ideas. Norrie wants to seek out new horizons, and Happy's philosophy is just, well, to be Happy. Tino's struggle for perfection inspires Tag, who decides his philosophy is that he wants to help people - starting with Tino.
