In the up-right corner of the first location there is a mini-level with a giant earth-lady. No instruction on getting the scenes is needed really, as there are only two encounters with her at the start and at the end of mini-leve
There's a tile called Valley of Giantess that has a Perception check. You have to fail it, and then there will be many opportunities, but for some scenes you will have to pass the Agility checks.
