Dennis and Gnasher are the noisiest and naughtiest presenters on Fun Kids.
They present a show every weekend from 9am-10am, and over Christmas they will be presenting special Christmas shows.
They will be packed full of the loudest music, silly chat and lots of mischief.
You can hear them from 24th December-27th December from 12pm-2pm on Fun Kids.
And you can also catch-up on all the Dennis and Gnasher shows from 2012 in iTunes and on the Fun Kids Player right now. Click here to catch up!
We’ve got loads of other stuff going on over the Christmas Holidays on Fun Kids to keep you entertained too.
