C'est quoi ce truc?

Lucas has invited Emma and Huan over for supper. While out shopping with his Mom, neither can agree on the menu. Lucas complains to Célestin. Mom´s ideas are all bad: fruits instead of cake for dessert, chicken without fries. And a pile of vegetables! Célestin assures him that Mom is only thinking of their health and adds that well-prepared vegetables are tasty. He suggests that Lucas invent a dessert. At suppertime, the children are enjoying the feast, and the girls are marvelled by Lucas´s pear mice.
