i'm so stupid pls help

so i was making a pond and went to suck up some water from another nearby water source... forgetting that 3 of my pokemon have habitats attached to that water source. i made all three of them homeless by accident 😭 i tried searching for all of them and none of them can be found anywhere. will they come back or am i screwed? i'm so stupid and sad LOL i didn't think before i did that
