This is a great little ad for Centre Parcs, by Electric Theatre Collective. I worked there in 2016, doing FX, mainly on this. Most of the time was spent on the vegetation on the whale and the soily ground burst when the robot first appears, as well as some secondary bits here and there, little bits of leaves, twigs, dust etc.
There's an excellent breakdown of the project here
