Spark Plug wires melted

hi guys ive searched this forum and searched google on a solution on this issue. Long story short my girlfriends camry overheated and motor started running really rough. so i got it home and pulled the spark plug wires out and cylinder 2, 3, 4 wires were stuck on the plug. twisted it and that still did not work. So i pulled as hard as i could and i found out the boot and some plastic from the wire melted on the plug. i got most of the plastic off but there is still the boot in there and cant get it out. I tried long needle nose pliers and it wont budge. has anyone had this issue before and if so what did you do to get them out?? This is driving me crazy. sombody hellllllpp me.
