Seed for already finished underwater temple?

I wanted to ask you if there's a seed for Minecraft where the underwater temple is already filled, or there's a map download. Because I try on my single player for 5 hours to get away from the water with sponges and I'm only at a tenth or so.

No, there's not. Even if it were a coincidence, nobody would know this seed. But it will not be a coincidence. It is not groundless of the underwater temple. The rough environment will be similar in each seed.

Change your approach.

Underwater temples are unspectacular.

Yes, but it takes hours to dry.
