Hi, guys, Jenny here, with how a fatberg as big as a plane

blocked this underground sewer, plus:

Find out what the ex-England captain thinks of the brand new one.

Before all that though, it's been the first day back at school, for

And for so many that's involved the big step up,

That can throw up all kinds of new challenges, so to help you out, we

got the kids that went through it last year to give you a few tips.

Starting high school is very scary, but as you get along the year, it

gets easier because you meet new friends.

Ask your teacher and your teacher will help you. As you get further

on, you need to remember it and maybe have a check list to make sure

you've got everything. maybe have a check list to make sure

You would need stationery, like pencils and rubbers, Willows. Just

basic stuff like that. -- rulers. And you would need a PE kit. Once

you get to know the school you will know your way around. You can ask

your teacher or you tell a parent or a friend. They will help you. You

just have to go up to them and say, start the conversation off by saying

what primary school did you go to, and how old are you, what is your

name, stuff like that. With this advice, I think I will be more

confident when I start secondary school. It is going to be a bit of

advice about how to keep yourself safe and make yourself more

confident. You can get loads more info on

starting secondary school over on the Newsround wesbite, so good luck,

guys, we hope your week goes well. Next, Wayne Rooney has been

officially unveiled as England's The Manchester United striker was

picked to replace Steven Gerrard this afternoon, ahead of tomorrow's

friendly match with Norway. It will be a special moment for

myself and my family, it is a great honour for me, I love playing for my

country, I would honour for me, I love playing for my

for anything less than the best. That is the aim for me and the

manager. Well, Wayne's proud,

but will he be any good? Here's what one former

captain thinks. I am proud to see him as the

captain, I think he is the most experienced player in the team, with

Steve is stepping down as captain and Frank leaving as well. He is the

most experienced player, a player that young players look up to and

will look up to. He will be very proud of being England captain.

Next, hold your nose, because we're heading to the sewers, where

workers have had to take on a giant fatberg the size of an aeroplane!

This whopper formed under an 80-metre stretch of road in London.

It's made up of a mixture of congealed fat, wet wipes

and rubbish, either flushed down toilets or washed into drains,

that stuck together to form a big block. Lovely!

A team spent four days using high powered jets to break it up,

and making sure the sewers didn't overflow.

This is one of the biggest sewage treatment works in the country and

this is where the sewage is supposed to go, but when you have a huge ball

of fact made up of leftover cooking fat poured down the sink, wet wipes

flushed down the toilet, it can't get there.

Finally, to the amazing rescue of a dog whose owners thought

This is the incredible moment Sprig the springer spaniel was rescued

at the foot of some of the UK's highest sea cliffs.

He'd been missing for ten days but was spotted

by a volunteer lifeboat crew, on the edge of the cliffs, by chance.

The crew then reunited him with his owners.

I had done quite a few rescues but this one had a nice ending. It was

tricky, but I managed to do it OK with all the help from the volunteer

crew. It was a horrible feeling not being able to find him. We just

cannot believe that he has been rescued.
