you can store special monsters in the storage vaults, but you cant store puzzle pieces. I hope they change that. 1/2 of my main box is full of puzzle pieces. its so frigging annoying, as I keep doing the monster grab (have probably done it a 1000 times) but it keeps completing she same 3 monsters over and over again, but not the other 20 or so super monsters where Ive gotten between 1 to 3 peices (and the reason why I keep spinning).

its probably a "scam" to keep people spinning.
