Ricky visits Kenya's largest refugee camp to find out what it's like for the children who are living there.
The drive from Nairobi to Dadaab - the biggest refugee camp in Kenya - should have taken nine hours. But team NR had a bit of a setback when one of the car tyres burst!
This is the first stop for people arriving in Dadaab. There are long queues of people waiting for supplies, including food, water and blankets. There are also lots of animals - especially donkeys who are used to move supplies around the camp.
The centre of Dadaab is really busy. These footie fans told Ricky they love Chelsea and Arsenal and still get to watch matches on TV. None of them shared Ricky's love for Spurs though. And one of them thought he looked like Harry Potter!
Dadaab's refugee camp has been there for about 25 years and is pretty overcrowded. Loads of new people are arriving every day because of the recent drought affecting millions of people in Somalia, Kenya and other neighbouring countries.
Because Dadaab is so overcrowded, lots of people sleep in makeshift tents on the outskirts of the camp, like Hussein. He's from Somalia and travelled to Kenya with his mum five months ago.
Their tent is made from scraps of fabric and paper, and Hussein told Ricky it can be pretty scary to sleep in at night. That's because there's no protection from wild animals and there are loads of strange noises in the desert.
Ricky met up with one of the local doctors who said they give everyone a health check when they arrive in Dadaab and make sure they get the right medicines and food.
This is cameraman Darryl and producer Charlie in action as Ricky chats to some of the children living in Dadaab, at a play area set up by the Save the Children charity.
People try to live as normal a life as possible in the camp, and that includes going to school. Loads of new students, aged from five to 19, arrive every day to join the lessons in Swahili, English, maths and science.
