Trainers, Snorlax’s spawn rate increased and you can find Snorlax sleeping at the moment.
The Normal-Type Pokemon from Gen 1 Snorlax has fallen asleep in
Pokemon Go and it seems like no one can wake it up. If Snorlax wakes up, he will be gone for good!
The Sleeping Snorlax will be available until June 3, 2019 at 1:00 PM PDT and once caught, it will be awake and ready for battle.
This is not a glitch, as the code for the Sleeping Snorlax was added recently.
