Crossover
As promotion for Shrek Forever After 's British terrestrial television premiere on BBC One, Shrek himself appeared - albeit not visibly - in the Christmas ident It's Showtime, which also featured the Eleventh Doctor and the TARDIS. During the ident, Rob Brydon and Sarah Alexander, whilst overseeing preparations for Christmas at the BBC studio, go to see Shrek in his dressing room trailer on the studio lot. Alexander informs Brydon that Shrek has a cold, as the ogre sneezes, sending a projectile blob of green snot flying through his door that lands on a large painted portrait that is being carried past, after which he can be heard saying "Oh, sorry!"

Additionally, Shrek and Doctor Who were also represented together in Funko Pop! Blitz.
