Where is Lapras?

Before I posted here that I wish I never encounter
Lapras, Charizard, Schyter or Golbat when It was G1.

My reason before is I can reach them or can't even hit them. And its so frustrating when they never fled but I'm running out of balls....

So I buy a new Phone with Gyroscope in able to activate AR mode.
- Just a coincidence that there's a WATER FESTIVAL so I grind some more extra time a place where water type pokes often spawn. I'm also excited to meet Lapras once again and try my new phone if I can catch/hit him/her but Psyduck, Tentacool, Magikarp, Poliwag and so many water type even Wartotle and Croconaw appears but where is that Lapras...
"Where are you Blue Fat Monster?"

P.S. I can easily catch Schyter and Golbat right now...
