While Fatou is helping Roger repair his vessel one day, the crabs bring him a very important part of the space craft. Awesome! Except that during a moment of (as usual!) clumsiness, the part gets lost and swept away. After a mad rush to recover it, which they do, they realize that with this spare part, the space vessel actually works! And with this news, Fatou also realizes what this really means! That if the vessel is repaired, she will lose her best friend…too bad if he wants to leave, there’s no way that Fatou is ready to say farewell to Roger…
