In the conjunction with the announcement of a new Pokemon game coming in 2020 - Pokemon Sleep, Niantic has released an event in Pokemon GO called, Snoozing with Snorlax.
This event begins on May 28 at 6 p.m. PDT (May 29 at 9 a.m. GMT+8) and ends on June 3 at 1 p.m. PDT (June 4 at 4 a.m. GMT+8). During this six days event, Snorlax will spawn more frequently in the wild for Trainers to catch. Snorlax caught will wake up and know the exclusive move - Yawn.
However, there are tips and tricks to catch Snorlax.
You may encounter Snorlax with low and high CP (Combat Power). Generally, you will think of using a Great Ball or an Ultra Ball to catch a high CP pokemon. But in this event, you could just use a Pokeball to catch any Snorlax regarding of its CP.
How?
The first and second ball throw is guaranteed to break out, which means that you do not have to waste throwing berries or Ultra Ball in your first and second ball throw. However, the third ball throw will guarantee you a successful catch.
You can use normal Pokeball on your first and second attempt. Then only use your Pinap berry (or none) on the third attempt as it is a guaranteed catch. You can also just use a normal Pokeball on your third attempt and it will still be a guaranteed catch.
