0:02:04 > 0:02:07And I basically just try and teach them.

0:03:20 > 0:03:21Here's Martin with more.
0:03:21 > 0:03:24If only there were somebody tall enough to reach our bowl.
0:03:24 > 0:03:25Gerald!
0:03:25 > 0:03:30Yes, we all love a bit of Peppa Pig, don't we?
0:03:30 > 0:03:32The cartoon is shown in more than 180 countries,
0:03:32 > 0:03:35in over 40 languages and is set to get even bigger because
0:03:35 > 0:03:38the much-loved show has been turned into a movie and will be
0:03:38 > 0:03:39hitting the cinemas.
0:03:39 > 0:03:46Four years ago, we spoke to the girl responsible
0:03:46 > 0:03:48for bringing Peppa to life.
0:03:48 > 0:03:49Hello, Newsround, I'm Harley.
0:03:49 > 0:03:50I'm ten years old.
0:03:50 > 0:03:52You may not know my face but you've definitely heard my voice.
0:03:52 > 0:03:56Cos I do the voice of Peppa Pig.
0:03:56 > 0:04:00Harley is now 15 and she is still the voice of Peppa.
0:04:00 > 0:04:08So, how did she become the voice of our best-loved piggy?
0:04:08 > 0:04:10I went to an audition for it.
0:04:10 > 0:04:13And they listened to my voice and I sound like a pig,
0:04:13 > 0:04:14a four-year-old pig!
0:04:14 > 0:04:24So this is how I am talking naturally but when I go
0:04:28 > 0:04:30I have to go a bit higher and I need to
0:04:30 > 0:04:31take quite big breaths.
0:04:31 > 0:04:34George, if you jump in the muddy puddles, you must wear your boots!
0:04:34 > 0:04:37Harley has some other cool tricks to show off in the future.
0:04:37 > 0:04:40I really want to be in a Marvel film.
0:04:40 > 0:04:42Something really cool like that because I'm a kick boxer,
0:04:42 > 0:04:44I'm a black belt in kick boxing.
0:04:44 > 0:04:46I've been doing that for ages, so Peppa is a black belt.
0:04:46 > 0:04:54Don't mess with Peppa Pig, then!
0:04:54 > 0:05:01That's all from me, Newsround's back from 7.40 tomorrow morning.
0:05:11 > 0:05:12Hey, Lifebabblers.
