From the Super Mario Wiki
The Earth Crystal is an enemy encountered in battle alongside the optional boss Culex in Super Mario RPG: Legend of the Seven Stars. Like Culex and the other crystals, they are from the dimension of Vanda and met in a portal leading to that world found in Monstro Town.
The Earth Crystal has the highest amount of HP out of all of the four crystals, but balances out with a dismal defense of 70.
It is weak against Thunder-based attacks.
