A found a stronghold in minecraft bedrock edition that was not under a village

A seed can't be poop. It has to be a number. You can type in "poop", but when you load up the world, the letters translate into numbers.

Strongholds don't always have to be located under villages. They can be found pretty much anywhere, under the ground, or ocean. But you do have a greater chance for a stronghold to be located under a village.
