Best Plunger for fitting Toto

My broad-ended typical rubber plunger won't mate with the Toto Drake toilet throat very well, as it is round and shallow, and the thoat is squarish and narrow, so I cannot get a good seat.
Although clogs are extremely rare, we had our first today, and all I had that would work for this soft clog was a snake, which was overkill, and messy, for this application

Can you recommend a model or shape of plunger that works well with Toto's.

Thanks!
