Pi in the SkyThe gang spot what appears to be a meteor through Screwtop's mega-powerful telescope. It turns out to be an early space invention of the Professor's, hurtling back towards Earth on a collision course with Beanotown! Can Dennis and the gang save the day, or will Beanotown be destroyed forever.

When Pieface rescues Walter and Bertie from danger, Dennis leads the town in celebrating Pieface Day in his honour, and refuses to listen when Pieface tries to tell him it was all a big mistake. Walter uncovers the truth, proclaims himself the bigger hero, and declares it Walter Week!
