Some resources below based on this Peppa Pig video in French:
Peppa Pig Cochon Français L'anniversaire De... por Zy-Video
The resources are based on a description of what happens in the story, rather than on the transcript of the video itself (although some bits of text are taken straight from the video).
What age / ability group would be able to cope with this, do you reckon?
There are 9 pdfs and a TaskMagic3 Mix&Gap file (mtx3 - requires TaskMagic3; provides access to 18 interactive activities), all based on the text.
With TaskMagic3 you can create your own resources like these based on any text in a matter of minutes.
