What tool do I need for this BB?

It is indeed 16 notches, I've ordered the one Kermit linked, wish me luck!

It does say "Do not disassemble" on both sides, you know that, right?..

Once that sucker it's on, it's a lifetime commitment. The intricate engineering behind these BB's have gone down in bikelore, as soon as it's in, it begins to release it's fangs, spreading within the frames - making it its host. Any attempt to remove may initially seem successful, but installation of new BB's will not bear fruit. The grease will dry out, the bearings will pop, it'll eject the crankarms - because the frame treats it like a foreign element stuck within it, like a thorn stuck inside your crusted feet... It'll push itself out sooner or later, and come night time you'll hear the distinctive sound of spanners dropping unto the frame, pizza cutters squealing, clicking from a bottom bracket - it's calling for its host...

I'm afraid it's a goner.

If you wish to attempt to run another BB in this frame, I recommend to seek the guidance of Satan himself. Make the bike a tribute to pure evil, because the only thing this BB fears is Papa Diaboli.
