I really like the palm trees. Where can I find those?

I'm glad you like them! They are the Tropical Trees Default Replacements by Tvikisims over on Tumblr.

They have other posts for the other plants in the game and even more.

Thank you so much. Their house looks really nice and colorful. If the grunt family lived in a house like this they would've never gotten so depressed The plants outside look so cheerful.

I love this lot, it's perfect for the Singles! Which OMSPs do you use? I see a bunch of blue squares around the house, probably OMSPs that I don't have and I don't want to replace them all hihihi

This is perfect for our four Singles sims. I think Erin and Kristen are on the bottom floor, and the Alien sisters on the top.

Thank you! I don't think I used much if any omsps but the ones I use are Full Range Shiftable by SilentLucidity. I do also have default replacements for all house plants but those should have just gone back to their normal version if you don't have those in your game.
I'm not too sure why you have those on your lot and I'm sorry I can't really help much. If they're still there after trying out the omsps I have, I would just recommend deleting them.

I'm happy you like it! It is very a very cheerfull house because I love playing with these four girls, haha. As for the grunts, maybe the boys will want some greenery in their lives after they move out on their own, haha.

You got it! Now you just have to decide which color each one gets. :p

Hi so I love all the houses you have done, I have greatly enjoyed my updated strangetown! I did want to let you know of an issue I have in your houses however. Every plant has a blinking blue tile under it. Now if I copy the plant and replace it with a new one its fine and no big issue, just thought I would let you know as I've only had it in your builds, great stuff though!

Thank you for liking these! I'm glad that they're serving their purpose of making Strangetown a little more updated. I do know about the blue flashing and I'm sorry it happens. That is because at the time of building those lots, I had plant default replacements in my game. I didn't realize it at the time how it would affect the lots after I uploaded them for people that didn't have them in their game. That was a newbie error on my part. I think it has to do with the shadows on the DFs plants or something.
I do want to go back and update the files in each upload when I get the chance but in the meantime, I think that only way to really fix blue flashing is to delete the plants and buy a new one.
Sorry again and thank you!
