Crystal

Crystals are found in large numbers across the Gobbo Archipelago. The number of crystals that can be found is directly linked to the high volume lava around.

Formation
Crystals usually form from molten rock as the molten rock gradually cools. If the molten rock cools very rapidly, then either small crystals form or no crystals form. An example of this is when lava is ejected from a volcano. If molten rock cools slowly, then large crystals can form. This happens usually when the molten material is very deep in the Earth.

Usefulness
Crystals can be very useful. For example, if Croc collects 100 crystals, he gains an extra life. The coloured crystals that are scattered across the islands as well are very rare, but enable Croc to open doors at the end of levels to get the sixth Gobbo availiable from that level.
