What's your lockdown 2:0 hobby? Are you trying your hand at baking, painting or...ballroom dancing? 

Whatever you're taking up this second lockdown, there's one thing that will put a smile on your face. 

Yes, it's that time again. Everyone's favourite bear, Pudsey, is here to brighten up your lockdown. And this year BBC Children in Need and the iconic yellow bear are gearing up to celebrate the charity’s 40th year! 🧸🎂

We're joining our friends at BBC Strictly Come Dancing and BBC Children in Need and we want you to join the party! 

This weekend, we have launched a new hashtag challenge #StrictlyCIN where the Strictly stars will show off their best moves to support BBC Children in Need’s 2020 Appeal.

Each day, a host of Strictly stars will post a new section of a dance routine on the BBC Strictly TikTok account for you to learn, recreate and reimagine at home. In fact, we are challenging you to use our Duet or Stitch features to show them what you've got side by side.

Claire Hoyle. Commercial Director, BBC Children in Need, said: "We are delighted to be working with TikTok and Strictly for a brand new challenge to get the nation dancing together. Get practising your moves for the chance to feature on Friday night's show!"

Money raised through BBC Children in Need’s 2020 Appeal will help children and young people across the UK facing disadvantage.
