Is it time for a Plumber or can I try taking toilet apart?

UPDATE-Help My Grandson flushed a 2 inch plastic toy in toilet. It partially flushes, but water almost overflows before I shut it off. I need help! Thanks you for your comments! Additional Details THANKS FOR THE PAST SUGGESTIONS EVERYONE! I TRIED THE WIRE HANGER AND I HAD AHOLD OF IT WHEN ALL OF A SUDDEN A WHOOSH SUCTION SOUND AND ALL THE WATER WAS GONE. DOES IT MEAN IT'S STUCK WAY DOWN NOW? STILL READY TO OVER FLOW WHEN I FLUSH. I'M GLAD WE HAVE 2 BATHROOMS! SHOULD I TAKE THE TOILET APART? OR IS IT TOO FAR DOWN BY NOW? I CAN'T AFFORD ONE, BUT IS IT PLUMBER TIME? UPDATE- I FINALLY HAD A PLUMBER TAKE APART THE TOILET. IT WAS STILL STUCK CLOSE TO THE OPENING OUT OF MY REACH THOUGH. HE HAD A HECK OF A TIME, BREAKING THE TOY FINALLY! THANKS FOR ALL SUGGESTIONS!!
