The Ace of Spades is a playing card from Thru the Mirror, a Mickeyjunk Mountain resident, and Oswald's right-hand man. He's the one that tells Mickey to complete the three challenges.
- "Oh, it's you. You're not getting in to see HIM. Not unless you pass some tests."
- "Here's the first test. Prepare to have your ticket punched."
- "Not bad. But you'd better be of the right 'caliber' if you're gonna make it through the next one."
- "I can't think of any witty puns for this last one. Just jump through the Projector Screen, okay?"
- "Oswald did it in half the time, but I guess you can go on through."
