It's Children in Need and we want to know what you're doing to help Pudsey with his fundraising.
Lots of celebs are getting involved - Matt Baker from The One Show is cycling a rickshaw from Edinburgh to London, and Alexandra Burke is trying her hand at clothes designing.
Are you doing something at school or with your family and neighbours? Perhaps you're having a non-uniform day at school or doing a cake sale?
Whatever you're doing, let us know! If you've got any great pics send them in to us at email@example.com and we might use them!
And who knows, Newsround may even come along and film it!
Thanks for your comments. This chat is now closed.
