Ran a query to create a table, now can’t find table

I just installed the user activity plugin, and had to manually run the query to set up the table, but I didnt choose any databases when I did so I have no idea where it went. I have multi-db with 256 dbs, is there any way to find where the hell the user_activity went? I would like to move it to wpmu_global

I used to have a script that would list all databases and all the tables inside them (hack job, but it worked since I’d just use FF’s search function and find whatever I was looking for), but I lost data and now I dont have that script anymore.

Is there anything I can do to find it? Or can someone help me get another script like the one I had? Thanks.
