Dryvit or Stucco?

So, one of the ladies at my church has a modular home that has some sort of weird siding. There are holes in it, and it's causing heat to escape from under the house. I think it's either Dryvit or Stucco.



I'm not looking to do a perfect repair job, just one that looks decent at a distance(I don't want to spend more than 2-3 hours on this).
She had a cat get stuck up under there as well, so it does need patching.
