It's not the first time I've seen Kayla's golem. When I returned to human world, before coming here, Kayla practiced controlling this golem with me as the sparring partner. Since she's trying to defeat a Werewolf, she used me as a practice target since my speed is quite comparable to the Werewolves. Though I don't know if they are still hiding their power or not at the time.
I can say that Kayla can control the golem smoothly now. But the price for that is the ugly appearance of the golem. It's just giant tube-shaped earth, on top of another tube, connected to the giant tube-shaped body.
For the sake of improving endurance of the golem and the smoother control over the golem, she has to sacrifice the look. I'm not talking about the beauty of the golem's appearance, but other things like joints for better movements of the golem as well, the reach, and yeah, maybe the looks as well.
