Those screenshots are pretty cool! Unfortunately, those are from the pre-launch or beta. This Reaper character or aspect of the game is no longer in The Sims Mobile, and hasn't been since launch day in March 2018.
Thanks for sharing though!
I agree with the OP with elder townies sticking around for too long. My town NPCs are pretty much all elders -- it's pretty much a retirement community 😛
With so many elders wandering around my younger sims can't find dates unless I fix up one of the oldies but they still walk hunched over
