The cool thing is, with Bolt's magic being much stronger, she can likely revert to her incredibly tight self with ease, unlike Fey who prefers to be permanently gaping and loose.

There's some advantages to really tight fairy holes.

The even cooler thing that has hardly been exploited yet is what they can do with Alex. It's fairy magic that keeps her together, so with Bolts help and a few excited clappings for a power boost, she should be as good as new.

I'd vote for some 3d puzzle games.
