Grisu: Special Delivery

OBSAH

To help David who has to take off for a firefghter operation, Grisu offers to bring a package to the post office. Even if the package matters a lot for David since it's a birthday present for his best friend, the mission shouldn't be too difficult.
Except that, after an accident, the package ends up in Guellec's van, then in a field with playful sheeps. Grisu and Stella miss the mail and therefore have to deliver the package by themselves. What they will manage to do, thanks to Grisu's invention: a cart pulled by drones!"
