"Digit's B-Day Surprise"
When Matt, Jackie and Inez get stuck in the vortex of a cyberportal, it’s up to Digit to rescue them. He just needs to find the U.V.O. – the Universal Vortex Opener. But all the portals are jammed, so how’s he supposed to travel anywhere? Assistance comes from a surprising source – Wicked! Digit and Wicked must work together to solve the puzzling clues that will reveal the location of the U.V.O. But they have to hurry – if the kids aren’t rescued soon, they’ll dematerialize! Can Digit and Wicked find the U.V.O in time? And is there even a fraction of truth to Wicked’s claim she only wants to help out?
