At the beach, Gaspard does one goof-up after another. He wants to play with Simon but each time he turns out to be a real pain in the neck. He tangles up the string to the kite, makes his brother fall in the water after pushing him on the inflatable ducky-life-preserver...and finally, the cherry on the cake: Simon has built awesome sand castles with Maelle and Gaspard shows up, smashing the tower on one of them and totally destroying the other castle... Simon is an adorable little rabbit who’s surrounded by loving family and close friends - he has a little brother called Gaspard and his parents, Eva and André. His close friends, Lou and Ferdinand love playing together for hours and hours. They sometimes quarrel, as friends do, but it never lasts long…
