[Last Airbender] You got a water bender bending vines into a giant monster why not earth benders make giant stone monsters or worse fire benders making giant lava monsters?

Huu seems to need to be inside the plant monster to control it.

Earthbenders *do* cover themselves in animated stone armour, and presumably they could make it monster shaped if they wanted to, although it's mentioned that being covered in stone slows you down. This implies that yes, you do need to be inside it to make it move like a human.

Given this, trying to make a giant lava monster has...obvious flaws as a plan.
