I have searched and searched the web for this Disney Princess Castle Kit, I have a feeling it's no longer available. Does anyone know if this is for sale online anywhere?

Did you use Google?

I went to www.google.com and typed "disney princess castle cake" and there were a LOT of hits for the kits.

Try it.

Do you have a link to the exact kit above?  I went there, but I could only find this:

Not crazy about this one.

That is the Super Size Disney Princess Castle Cake Kit, and it is no longer available.  I even checked ebay.

I thought so--darn!
 

Sorry.  From amazon it looks like it was discontinued in 2009.

I HATE these silly manufacturers that come up with something catchy for kids, but they only have one production run at the factory.  And that's it.

I went through something simiilar when a friend's kid wore out his Peter Rabbit  bed set.  I went to every fabric store in a wide area and searched online, and never found the same pieces again.
