These bouncy ball toys were around in 2005. The company Tiny tins was going to make more series of them but for whatever reason they didnt, so it was a 1 and only series for these.
I'm not too sure but I think I have the most complete set. There was a website years ago with pictures that I uploaded but its since been deleted, I want there to be a record of these online for future generations to look at so if they here the term " BOOYAH BOUNCY BALLS" they will know what they are. Several people on Reddit have been looking for them.
The elusive Diamond bouncy ball, which was only a very limited special supply of 500 which you had to find a special card in the box and send it into the company.
48 regular bouncy balls each with their own tin and back story.
6 rare ones each with their own tins and a back story.
1 ultra rare Diamond, we never got this one so I assume it came with its own tin, would be silly if it didnt. Update : We were finally able to get a Diamond Booyah, thanks to a wonderful seller on ebay who put us in touch with a buyer who had bought all of his stock. He had 3 diamond booyahs so we bought 1 off him to be able to complete the full set.
