look with your eyes, bozo (little joke) music: lava reef zone act 1 from Sonic & Knuckles or Sonic 3 & Knuckles because underground thrice is three times, btw i may or may not have completely forgotten to say Earth has 300 HP
change the color palette to make it more brown also make cracks in the design. actual cracks. and the shards are like a shotgun a stone splits into 3 shards with a 10% chance stones becoming shards is all or nothing, so either they all become shards or they all stay stones Earth has 300 health and appears every two waves starting at wave 20. At wave 30, it appears every wave. At wave 35, it can appear twice in a wave (not every time)
