teleport to a ball

[Ariel]

i want to do some kind of skill to Earth that he get into the ground and than get out of the ground behind the enemy, but not just teleport i want to make it visible to where he goes
like firen fire run that he make road of fire behind him so when Earth get into the ground and follow the enemy u can see only a roud of rocks on the ground

so i kinda though about how to make it and i thought on making some kind of following ball like julian skulls and ill make it look like rocks on the ground
but now i need somehow to make it when it get to an enemy instead of hurting them it will teleport earth to them
