I was thinking about this whole situation, and I realized why there was a problem. See, I used to only have two candles that I lit while in the tub and they were both on the "inside" (the wall side) of the tub so Tubby couldn't get to them when he jumped up. He tried to get to that side of the tub (behind my head) but I would always stop him because a few times he almost fell in because it's a little narrow, and then he has to turn around which is also quite interesting. So, anyway, he normally doesn't get to that side of the tub, and that's why I put the candles there.

The problem came because I bought a new candle and put it on the outer edge instead of on the protected inner edge. I will now move that new one to the inner edge so there are no problems anymore.

I still say - whew!
