Well, my one year old is constantly chucking toys and loads of toilet paper into the toilets and then my three year old flushes it down for him before I get a chance to see what happened.

My 2nd floor "potty" is clogged up, will flush with plunger assistance.

I suspect that there is a hotwheels or something stuck up there. Would you advise that I take the toilet off so that I can try and clean this one out? What tools/brand should I use for this one?

Last thing I want to do is jam a toy further down the pipes into the system.
