Staff Energy Gem
Staff Energy Gems are small gems that grow on Magic Plants found throughout Dinosaur Planet in Star Fox Adventures. They are used to restore the Staff Energy Meter, which allows Fox McCloud to use of various Staff Upgrades. Different colored Gems restore a different portion of the Staff Energy Meter. These gems come in four colors that determine their restoration capabilities, from worst to best go as follows: green, red, yellow and blue. This of course means that the green ones are also the most common.
