Amazing disappearing Yum Yums
Yum Yum hoarders (Yes, I'm one too,) don't you just hate them? Don't you just want to slap them into Earth B? But in QAGS terms, what can you do to convince them of the error of their ways? (i.e. Use the freaking Yum Yums.)
How about if after an hour of game play, the GM said "Everyone, give me a Yum Yum."
Yeah, first they'd go ballistic. "This isn't fair!" But maybe, just maybe, it might spur the players on to do those "cinematic" hero things that earn them more Yum Yums (I am an optimist, you see.)
Eh, it's just an idea.
Put them in a situation
Put them in a situation where they need to spend Yum Yums. For instance, lock them (the characters, not the players) in a vault that is rapidly filling with deadly gas. If they want to find anything useful to escape, they'll have to spend that precious candy.
