I don’t remember that one...thank GOODNESS! I’d have been the same...afraid of my very walls!
I see the episode these days and laugh but it scared me badly when I was a kid.
I kept a pile of socks on the end of the bed at night. When I woke up to go to the bathroom, I’d toss one on the floor and step on it, knowing that was a safe spot. Did that all the way down the hall to the bathroom, then picked them up on the way back to the bed. No way I was gonna fall through one of those holes if one opened in the floor! ROTFL!!
I was an impressionable child apparently.
