This Object came with Seasons. The download is a unlock package you need CS to see something because the mesh textures and other stuff is in the Gamefiles. If you have Seasons you could use the attached CS_Sculpture_WishingPot_stone Recolor i have made for my game.
Here is a pic of the Seasons Wishingpot.
Actually, I was so absent-minded I forgot the extract the texture for it... I duno y but I do remember the last time I put the .package downloaded from CS site to Sims 2, it just worked fine with correct texture except that it overwrites the one from Seasons as they both share one GUID. And thx for the recolor... Anyway, I updated my version. Mine makes the stone wishing pot a separate object from the Seasons one.
