How do you beat peter in amateur surgeon on act 3

This is a very hard one. i supposed you alredy know how to use the tools. When you get to the inside of the stomach, go for the nest first, just use the etchey sketchy, and then cut . when you cut use the battery until you zap the spider, then get rid of the poison and heal the hounds. Repeat this 3 times (im no sure) and then go for the eggs. Deal with them separatly. Then Just Close Up. Hope this helps. Bye
