Buddy from the Future

Buddy is about to have a real adventure; he has come from the future in a time machine and looked at how his ancestors live. But now it's time for him to return home, and there's a small problem: to get to the machine, he needs not only to collect golden stars but also to properly stretch the rope to move around. Help him, think about which rope to cut and which to stretch so that Buddy arrives safely and intact exactly into the time machine.
