Draculaura was riding the bike through the dark Monster High forest, when she felt dizzy, all went blank and fell. Now she is in the ambulance, waiting for you to do your job and run tests on her. It seems that her calcium level is very low, due to the fact that she is a vegan. Use your tools, investigate her wounds, clean the blood, put bandages, do an EKG and make her feel better.
Use mouse and follow the hints to heal Draculaura.
