Mae hi'n amser Nadolig, ac mae Peppa'n edrych ymlaen yn fawr at ddrama Nadolig yr ysgol feithrin! Mae'r plant i gyd wedi gwisgo yn eu gwisgoedd gwych, ac ar ôl cyfarfod annisgwyl yn yr archfarchnad, mae Peppa wedi gwahodd Siôn Corn i ddod hefyd. Ond y Nadolig ydy'r amser prysuraf i Siôn Corn a fydd e'n llwyddo i gyrraedd mewn pryd? It's Christmas time, and Peppa is very excited for her playgroup's Christmas play! All the children are dressed up in their fabulous costumes, and after a chance meeting at the supermarket, Peppa has invited Father Christmas to come along. But Christmas is his busiest time of the year . . . will Father Christmas manage to make it on time?
