A Color Gem is a special, powerful and very dangerous type of gems that Dimensional Bloon created, each one has its weaknesses and strenghts. They are bosses in some tracks after you defeat the real Omega Bloon. These have lots of health, but you have the Omega Finder! They were created to test the power that Dimensional Bloon obtained in the Third Dimension. * NOTE: Gems are completely immune to SPIKES. * NOTE 2: You can only fight a Gem once.
