�"Here I Am!"
Loo-Kee was the little blue-tailed creature in She-Ra who would hide in the background of a particular scene. He would appear in every episode and, if you spotted him, you were, like, smart. And you would be watching for him because you knew he was going to pop up eventually.
At the end of each episode, the shot in which he had been hiding would be shown again and then he would point himself out. This was useful because he would sometimes be so fully integrated into the background as to be completely indistinguishable. Most of the time, though, his appearance in the episode was totally obvious, even bordering on jarring.
The point is, Loo-Kee is to She-Ra what Pharrell is to MTV.
