In a pre-show promo, Josh Duhamel was slimed while revealing that he was the 2013 Kids' Choice Awards' host. Duhamel was also seen bathing in a bathtub full of slime during the promo. During the show, Josh Hutcherson, Amanda Seyfried, and a group of kids appeared in a special green room to advertise the upcoming movie "Epic". They were slimed by Mub and Grub from the movie.
During the Show:
Pitbull – During the opening of the show, Pitbull and Christina Aguilera performed "Feel This Moment". Once the performance ended, Pitbull was drenched in a torrent of slime caused by Christina pushing a button.
Dwight Howard – Josh Duhamel challenged Dwight Howard to a basketball dunking competition. Duhamel made one dunk and Howard made the other and told him how it was supposed to be done. After Howard's dunk, the basketball hoop rained green slime on the famed basketball star.
Neil Patrick Harris and Sandra Bullock – During Neil Patrick Harris and Sandra Bullock's presentation, the two stars were covered in green slime while trying figuring out was Harris' special magic wand could do.
Josh Duhamel and Nick Cannon – At the end of the show, Duhamel and Cannon took part in a special zip line stunt to reveal the winner of "Best Male Buttkicker". After Dwayne Johnson won the award, he surprised the two stars with a grand finale of green slime all over them and the audience near the stage.
