The above solution is good, but for those that are like myself and like to have everything in one video, I've compiled my playthrough together below for a nice 1-hour 1k video. If you follow along, counting video watching time you can get the 1k in two hours or so. Timestamps for each Chapter/Level are below if you wish to skip straight to a chapter you're struggling with, or just follow along from the start of the video below the timestamps to do everything in one go.
This particular achievement is for the figurine in 2.3.
