The kids have their hands full trying to keep Rocket under wraps when the little alien dog gets a case of hiccups. Jack can’t take him home – Rocket’s bouncing about like a rocket everywhere and he’d crash the ship. They’ll have to wait it out on Earth. When the kids find out Rocket’s hiccups can last anywhere from 8?10 years, they insist Jack go into Rocket and find a way to stop the hiccups internally… before the entire neighbourhood is in on the secret.
