When visiting the Kangaroo family, Peppa is shown their fish tank which holds both a clownfish and a blue tang fish. These are the same fish species as Nemo and Dory from Finding Nemo.
The character of Daisy, played by Emma Grace Arends, first originated in the Peppa Pig's Big Splash theatre tour. Arends was asked to reprise the role for this film.
This is the second Peppa Pig 1 Hour Special!
