Near the middle to end of last year, Disney changed the way its Pixie Hollow Secret Codes worked. I think it worked out that everyone was sharing them instead of buying the actual products. Anyway, now they can only be used once I think, so its no use sharing them.
However, A FEW secret codes still work. They are:
106510: Rose Cami, daffodil yellow
130408: Sparkle Poppy Skirt, daffodil yellow
118337: Stargazer Pendant, watermelon pink
128288: Acorn Kettle, mint green
I'm sorry that all the old codes don't work anymore. They had some really awesome stuff, and I missed out on it all, too. :'(
There aren't any new 2010 pixie hollow codes. And the existing ones doesn't work either.
Yes
There are no new codes. All the ones you probably have entered by now.
There are no headband secret codes. Very sorry.
All codes are listed on the Disney Online Worlds Wiki.
There are no different codes than there were in 2010 rather than "derby" and D23.
406060, 667754, and 456467.
Here one... PPBQ4K752PSL6LLJ. This works, trust me! It will give you 55 raspberries!
Nothing besides the normal codes. There are new ones such as Derby and D23.
I'm sure its possible to but the codes for beds are extremely rare since the beds came on three years ago in 2008, when PH was first developed. Also in 2010 Pixie Hollow changed their codes so finding one that still worked would be even harder.
Other than the normal top and skirt, there are no new cheat codes or different ones. Derby and D23 are the newest codes, but aren't very useful.
You may have typed them in wrong, or, as of somepoint in the spring of 2010 (i think), they were replaced. The old codes no longer work. They have been replaced, and the old codes retired.
