My daughter did a similar thing but with a plastic toilet deodoriser, She was told to flush the toilet, but don't let it refill, you do this by holding up the ballcock. Then boil up a kettle and pour down the toilet, you made need to do thid several times. The Idea is that the plastic will start to melt and change shape and hopefully flush away. Hope this helps.
