anyone got the "ot trat something"?

I randomly clicked on a ball or something on one of the screens (this happened twice to me, first in "find 10" the other in riddle) and the whole screen background went away only showing the objects to find. Is this some easter egg or a bug or am I the only one who's seen this?

I've played this game forever ( or it just seems that way ) and I have never seen anything like what you have mentioned.

Ok, I took a screen shot, then had to crop it due to size, but here's what the clue was in Riddle:
