The This is It Collective is a group of designers/animators who have made a bunch of different videos. Their videos tend to have a simultaneous playful/unsettling/dark feeling, especially videos like:

“Dont Hug Me I’m Scared”

Their videos have a handmade and felt like look to them which gives the work an almost childlike feeling, but also have a high degree of craftsmanship and quality.

“Bad Things That Could Happen”
