Hideaway

Hideaway [Mount]

It was a plane, but now it's a bird, and it fits in your breast pocket.
Benefit: Your mount can assume a compact form at your command, to facilitate stealth and travel. The compact form is small enough to be hidden on your person in the same fashion as a [Hold-out] weapon. Causing the mount to shrink or return to normal size is a standard action. You cannot cause your mount to shrink if it has any occupants, and it can only return to normal size if there are sufficient unoccupied squares (at least one of which must be adjacent to you) for it to fit.
