I remember that there was another topic regarding the lake creatures but I did not bother to dig it up since my question would be totally unrelated in some way. Currently, my game character is still at Iron Island pumping the levels of my Pokemons from 60s to around 70. My next stop would of course be over at Lake Valor where I figured out I would be battling the lake creatures next.

Hence in order not for me to overtrained my Pokemons, resulting in a one- hit K'O. I would like to know what are the general levels of the lake creatures? Are their level be in the fifties or sixtes?

And also I saw quite a lot of discussion on the earlier topic on using Dusk Balls to catch those lake creatures, hence I was wondering where can I get those as well. Thanks.
