Kenny is a tiger shark who has found himself in the strange position of being a family pet. Kenny has all the characteristics and instincts of any other tiger shark, but he must adapt himself to the placid ways of suburban family life. If not, he`ll be put back out to sea, which would mean giving up his best friend Kat, which would be unthinkable! Kenny is about an 8-foot, 1,500-pound tiger shark who lives with 10-year-old Kat and her family in the suburbs. Her parents are tolerant of Kenny, but he`s big and smelly. Luckily, Kat speaks shark, so she tries to reason with Kenny when he wants to eat the mail or mail carrier. If Kenny can`t adapt to life under a roof, he`ll have to go back to the sea. Kat learns that living with a shark isn`t that easy since they eat everything, they never sleep, and they constantly shed their teeth.
