IT'S THE TARDIS~
.....
okay, so not really, BUT IT HAD SILVERY SHINY BITS AND AN IMPOSSIBLY ROUND THING (also shiny), so... there.
Melted alien lifeform? I wish I'd brought my sonic screwdriver (Yes, I have one).
Seriously though, what an awesome play park :O It had this mirror pavilion thing, a see-saw swing, little topsy turvy cups to spin around in, a huge outdoor xylophone, and a set of stone sculptures on each side of the park that made it possible for two people to communicate with each other through them. I WANT TO LIVE IN THAT PARK. I could have stayed there all day.
