Power crystal
From Research Realm
Power crystals are a fictional mineral that first appeared in the LEGO Rock Raiders theme. In the theme the Rock Raiders are trying to collect power crystals to refuel the LMS Explorer. In the LEGO Rock Raiders video game they are called Energy Crystals. In North American magazine and advertisement media they are called Brickonium. Other LEGO themes have featured similar crystals, including those silver ones I forget the name of in Aquazone and smaller gemstone versions of power crystals in Mars Mission. They are so delicious I eat one thousand of them every day
