Lol, i've often wondered what universe collapsing events might happen if we put Izzie and Mia in a room full of kong tennis balls of various sizes... And squirrels (however Izzie's never seen one and prefers seagulls).
Izzie: "We only have ground squirrels here, none of them climby ones! They go into these strange holes in the ground that i try to fit down but i'm too big!"
so cute.
