Collider:

As Nickelodeon announced today, the series will be returning for 40 all-new episodes this summer, and will feature both classic challenges and new ones. The press release explains that, “Double Dare features two teams competing to win prizes by answering brain-bending trivia questions, completing messy, physical stunts and ultimately facing the infamous obstacle course—the human hamster wheel; the classic gigantic mouth; the wringer; and the iconic Double Dare nose."
Fingers crossed that Marc Summers gets the gig.

If not him…well, I have some experience hosting ridiculous, silly game show type events.
