Oh what terror trio! Filou (of course him) had an excursion like that in summer. We had not noticed that there was a chance for him to leave not just the apartment (which he has managed more often) but also the house So we were looking for him everywhere and after 2 hours we thought about opening the house door and there he was saying:" It was a nice excursion but now I'm hungry". We hadn't even time to worry but as Filou is a specialist in dematerializing (you can search him for hours even in the apartment) we are relly afraid of the next time.
