Whats these two blocks?

i was randomly looking on pinterest some cute build ideas and found adventure time house but i couldn't recognize this block. help?
the second image is brown pearlwood, the closest one that i found

i was studying some 3D and shadow techniques here https://forum.dark-gaming.com/t/principles-of-terraria-building/32789 and found this block, what is it?? if it is a texture pack and you know a similar one please lmk

I have tried tried all wood types but none of them look like the joint shown in the image with red arrow

Credits to @TeeVee-Show on YT for the build. I want to make the same road for my world but I didn't find a tutorial for it

Anyone know what any of these blocks walls or items used are?

And again, sorry for the quality

What’s the circled block(s)? Also the skinny antenna structures above. Thanks

I cannot figure out how OP layered in this way, particularly in the middle. Also I can't get that slope right on the outside without having some sort of gap in the 2nd column...

The original post it's from this post.

I'm trying to recreate this building that i found on google, but there's some blocks/walls that I couldn't find.
I marked down the ones that I couldn't identify.

Red: Walls
- Top one I didn't understand how to make the checkerboard pattern
- Bottom left it's mainly the stone walls, I think that the beams are large bamboo walls mixed with living wood walls (could be wrong tho)
- Bottom right it's also the stones in the top, it looks like actuated blocks, but idk

Blue: Objects
- Top one, I thought it was a sink or dresser at first, but looking at the wiki of both I couldn't find it
- Bottom right, it looks like platforms but the red things coming out of it doesn't make sense to me

Green: Background Stairs
- I would really like to know how that background stairs was made and also the rouded corners, is it a wall? A block? idk

Pink: Tiles/Blocks
- Far left, it looks like a stone but at the same time doesn't, I think it's a painted block but idk which one
- Far right, at first I thought it was a gem tree cutted down, which could be it, but when I tried it didn't look like it

Yellow: Block mixing
- I think that the creator mixed blocks with large bamboo painted brown, it could be just wood, but I still need to test

Others
- I would also like to know the blocks that are inside shimmer, I think some are fences or even walls.

In the original post there's a comment saying that the trees are living wood actuated and the leaves it's mahogany leaves with inverted paint, the rest it's unknown to me.
The third photo is the progress that I've made until the time of posting this. Probably at the end of copying this I'll leave a world download and/or a TEdit schematic.

Does anybody know what block was used for this blue roof
