Ohh, yeah! I remember this logo quite painfully. As a child, somehow the beyond eerie sound used to cause me nightmares... And it still causes me nightmares now and then.
I remember this was on Zoom. I was scared of a lot of things when I was little, but I was never scared of this. The thing that scared me for my entire childhood was the Eat n Park ad right before Mr. Rodgers *shudders*
