The fourth episode in the series sees contestants Robbie and Debbie joined by four celebrities hoping to help solve a range of rhyming rounds. In the first team are TV presenter Angellica Bell and radio and TV presenter Roman Kemp. Making up the second team are comedian Vikki Stone and choreographer and dancer, Wayne Sleep.

A fun, play-along family game show all about rhyming. Contestants Matty and Ruwaydah are joined by 2016 Strictly winner Ore Oduba, Hollyoaks actress Jorgie Porter, comedian Tom Allen and actress and presenter Linda Robson. Ruwaydah and Matty first go head to head in a quick-fire animated rhyming round, at the end of which the one with the most points gets first pick of the two celebrity teams, before they move on to play Mime the Rhyme. As Jorgie and Tom describe a celebrity, Ore and Linda mime a rhyming action to the celebrity name.

Next it's on to Rhymewatch, where the teams attempt to identify all the rhyming pairs within a short film starring Strictly judge Craig Revel Horwood. Finally it is time for News at Len, where the teams must guess the rhyming headline in four fictional news stories.

The contestant with the most points after these rounds goes on to play Rhyme Against Time, where they must solve six three-part rhymes against the clock in order to win a holiday.
