Morph Ball

The Morph Ball is an amazing feature that Samus Aran is able to perform in the Metroid series of video games. While many have tried to duplicate it, most notably the Space Pirates, many have failed to do so seeing the amount of deaths that have resulted. It was crafted by the hands of the Chozo species, who added it to their Power Suits that Samus wears.

Once Samus goes into morph ball mode, she and her armor will shrink to the size of a small ball, and will then be able to travel that way, fit through tight paces, lay bombs, travel up walls if they have a spider-track, boost, and do other things as well. Usually in games she'll either 1. have to find it at the beginning of the game or 2. have it at the beginning of the game, though quickly loose it, requiring you to go back out and find it again.

Spider-Ball
The Spider-Ball is an addition to teh Morph Ball mode which allows you to travel up certain walls that are plated with Spider-Ball tracks. You are required to obtain this item in the games that feature it, as it'll usually lead you to areas that otherwise can not be entered.
