Ooze

Ooze is what Pin sweats, when she is nervous or tired. It only appeared in Get Digging and Get in the Van. Instead of sweating water like the other objects (except Firey, who does not sweat at all, most likely), Pin was revealed to be sweating ooze, and not water.

Trivia

 * It was revealed that Pins sweat ooze, not water.
 * However, in Take the Plunge: Part 2, Pin is seen sweating water.
 * Apparently, Pin eats her own ooze.
