Had no idea where to post this so sorry if its in wrong spot.
Ive been hunting for an abra north of the day care place ( i think its the day care house ) and ive found 3 abra's in about 2 hours. 2 of them i tried throwing a ball and they both failed and it teleported and the 3rd i tried putting it to sleep but it teleported before i could sleep.. so was i just unlucky to not get the first hit to sleep it or do i just have to throw the ball first time every time and hope i get lucky?
