Mehmet and Samson are playing soccer when a wolf asks them if there are any mountains nearby. Samson says there's no mountains around and the wolf is relieved. The wolf turns out to be Willy Wolf, the famous mountain climber. Samson is impressed and thinks one has to be courageous to be a mountain climber. Willy tells him that you don't just need a little courage, you need a lot of it. Mehmet thinks it could be fun and Samson quickly says that they can use his cave.
