I mean it was stolen by Syrup from Peach's castle first if I recall, Wario heard about it and tried to find it first but Mario yoinked it back as soon as it got revealed.
And it's not like Wario cared, he had a fucking genie.
A genie that for some reason needed money and all his treasure for him to finally get a castle of his own instead of having to steal Mario's when he was out in Sarasaland saving Daisy.
