These are default replacements for the Aquatic/Underwater kid's bedroom objects from Family Fun Stuff. Since they replace objects in Family Fun Stuff, Family Fun Stuff is required.
The replacement textures are from Michelle's YETI recolors
of the Aquatic objects. (Michelle lists the names, prices, and catalog locations of the objects.) The TXMTs are replaced with ones that use the values in Michelle's recolors. There are five replacement packages, one for each of the five color sets that Maxis made, so you can replace any or all of them, as you choose. In addition, there's a package to replace the base of the Stinging Jelly Light with the white recolor that Michelle made for it. Screenshots for the color sets that have replacement textures for the Stinging Jelly Light show both the Maxis base and the white base. (Since Maxis only made three recolors for the Stinging Jelly Light, the packages for the blue-and-white and light green color sets don't have replacement textures for it.)
The light green, gradient blue, and gradient green color sets (lightgreen, gradeblue, and gradegreen) are replaced with Michelle's YETI Inchworm, Nile Blue, and Palm recolor sets. The blue-and-white color set (bluewhite) is primarily replaced with the YETI Pool set, but the bed and rugs have been edited by me. The bed frame and the spots in The Pounding Waves Rug are from the YETI Snow recolors, and the stripes in The Fishy Rug are from the Nile Blue recolor. Rather than try to follow Maxis with the blue-and-pink color set, I reimagined it as sort of pink-and-white, and used the YETI Petal recolors, with edits to the bed, rugs, and lamp. The bed frame, the spots and stripes in the rugs, and the lower part of the lampshade are from the Snow recolors.
The Buy Mode catalog thumbnails and previews will likely show the Maxis textures unless you use ctrl-right click to refresh the thumbnails or allow the game to regenerate ObjectThumbnails.package.
Not long after Family Fun Stuff was released, windkeeper made texture fixes for some items in the blue-and-pink
and gradient green
color sets. If you still see Maxis textures after installing the "pinkblue" or "gradegreen" replacement packages, it probably means that you have the fix for that color set, and will need to delete it. If you need to do that, look for wind_FFSaquaticsetpinkfix.package and wind_FFSaquaticsetgreenfix.package.
Here's a close-in view of the lamps, so you can see how they look when lit (top) and unlit (bottom).
