I'm currently looking for a no autonomous splash puddles mod. It's been driving me nuts when one of my families tried to put one of the toddlers outside so that they could splash in the puddles.

Is there anything here (or elsewhere) that would stop that?

I don't recall seeing one but it should be easy enough to make. It'll be a tuning mod.

Seems like this should be reachable with Retuner.

But for a standalone tuning mod, Chicken0895 has one at The Sims Asylum.

Good Morning .. Here is the settings igazor mentioned for Retuner
Splashing In Puddles Settings
Using Retuner:
From City Hall or any computer > NRaas > Retuner > Settings > General > By Object > Terrain > SplashInPuddle
From there you may adjust various settings for this action.
Note: There is also an option for Play In Puddle under Terrain to adjust the settings.

There are more options for other settings to stop annoying behavior <a href="http://nraas.wikispaces.com/Behaviour+In+General">On This Page</a>

OK. Thanks for mentioning Retuner. I'll try that later today.

Retuner is THE BOSS.
