Thousands of parents and children packed into Queen Elizabeth Olympic Park for one of the UK’s biggest children’s festivals.

Although they enjoyed a variety of activities at the three-day LolliBop festival, there was no doubt who they had all come to see. Justin Fletcher, star of the CBeebies show, Something Special, received a huge roar from thousands of parents and children, many of whom were packed tight around the main stage at the park.

Parents hoisted their youngsters onto their shoulders so they could see Justin who is known to children as Mr Tumble. And he did not disappoint as he led the assembled fans through his well-known repertoire of songs and characters.

The BAFTA award-winning star performed live for LolliBoppers on Saturday and Sunday.

Dick and Dom got the audience involved in their zany antics while CBeebies stars Sid Sloane and Andy Day hosted their own Big Birthday Bash with songs and silliness.

The Transformer Optimus Prime truck proved to be huge draw for children who waited patiently to get close to the distinctly painted vehicle which turns into a mechanical superhero in the Transformers series of movies.

Youngsters also had the chance to meet a variety of children’s characters, try out various games and rides and when it all got a bit much for them, or their parents, there was plenty of space to sit down and enjoy a bite to eat.

The atmosphere in the Queen Elizabeth Olympic Park resembled that of a massive picnic and was at times reminiscent of last year’s Olympics with volunteers directing people to the site, engaging with festival goers.

The all-mouse reggae band, Rastamouse and Da Easy Crew, took to the stage on Friday. Last seen at LolliBop 2011, the cool, mystery-solving mouse performed his latest hits for fans throughout the day.

Another new addition to the LolliBop 2013 line up is everyone’s favourite postman, Postman Pat and of course, Britain’s most famous black and white cat, Jess.

Organisers of the festival said more than 45,000 attended over the three days, (August 16-18).
