this story is absolutely fun, the woman here who is as young as all the boys in this story fit to be a sister or a girfriend instead ends up being their mother, their father left some stuff for the inheritence after his death, so as the story goes on , it turns out to be a great and funny adventur also sort of a puzzel game to find more things one after other using small hints nd secret doors and stuff .The brothers were not united at the begining when the story starts but one after the another full of fun episodes they unite and become a true family as well along with solving those puzzels using crazing invented toys made by their father .And oh yes the ending song is just superb.
