Their "All That" co-star Lori Beth Denberg will also appear.
"I am so excited to be playing on 'Double Dare' and for whole new generation of kids to experience this iconic game show," Mitchell told Entertainment Weekly. "This episode will be double special because Kenan and I will be playing against each other and we are both huge fans of 'Double Dare!' I can’t wait to see the super talented Liza Koshy rock it as the new host!"
The former duo's "All That" co-star Lori Beth Denberg will also compete on the episode, which premieres later this summer.
The show returns tonight, hosted by YouTube star and actress Liz Koshy. But don't worry, the original host Marc Summers will be returning to give commentary on the challenges.
As '90s kids remember, the game show consists of trivia questions, crazy physical challenges and a slime-filled obstacle course. Something that will make you feel old: the show hasn't been on air since 2000. Welcome back!
"Double Dare" airs Monday at 8 p.m. ET on Nickelodeon.
