My kid flushed a rubber ball down the toilet before - it was exactly the right size and squishyness to get stuck. After trying many things, I was able to get it out by removing the toilet and pouring in boiling water - it softened the ball enough for it to be flushed out.
It sounds like I got lucky. It was a warm day iirc - maybe that helped with the thermal stress.
The thing is, you want the turn signal to turn on before the start of the turn, so other drivers, pedestrians, cyclists can react.
