SEASON 04, EPISODE 06: Yep, we went backwards; this aired before the roadkill satyr! This episode features eerie incidents at an old toy museum, with rumors of toys coming to life and attacking children. When the kids investigate, the haunting only gets significantly worse, as the invisible force controlling the toys begins to control human beings. Dazed and drooling, the victims shudder and dangle as if on puppet strings...
ORIGIN REVEAL:

We also don't have a clip to go by for the origin flashback, but the spirit's form is based directly on the man he once was, a grandfather who used his puppetry skills to entertain children at the same museum. When he passed away, he left the museum to his adult son, believing his legacy would be preserved.
Instead, as the museum struggled to remain open and attract enough visitors, the son began planning to close it for good, demolish it, and open a hotel in its place. Furious, his spirit began lashing out at even the museum's few child visitors, making the situation exponentially worse.
I'm not sure what exactly his family was supposed to do in the long run to maintain the place; I don't think the financial troubles were completely resolved here. Nonetheless, his child and grandchild agree to protect the museum at all costs as his soul ascends to the next life.
