Power Bracelets

The Power Bracelets are a set of power-enhancing items that allow Marty to lift various objects for purposes of exploration.

The Level 1 bracelet is obtained in Turtle Rock. Its powers are unknown because the player immediately gets a Level 2 bracelet after finding the first one.

The Level 2 bracelet allows Marty to lift tall statues and small rocks. It looks exactly the same as the Level 1 bracelet, and is even found in an identical-looking room. According to in-game text the bracelet will let you lift a whale. This is a lie, because Marty only runs into a whale at the end of the game and even then he doesn't lift it.

The Level 3 and 4 bracelets have no in-game function or sprites and were probably a coding mistake.

The Level 5 bracelet is found in Birdphone's Revenge and can probably lift the whole freaking planet at this point.
