The monkey has good memories of his school and often visits there to remember the old days and help if necessary. In Monkey Go Happy Stage 776, the heroine arrived at school for a reason. One of the students asked her about this. He suspects that several students in his class are vampires. This is a serious accusation that needs to be checked and you must help the monkey deal with it. To understand who a vampire is, just look at the preferences of the heroes. The boy who asked the monkey for help asks for protection for himself: a bunch of garlic and a cross. The rest of the heroes have specific requests that also need to be fulfilled in Monkey Go Happy Stage 776.
