Pokemon Sword and Shield saw the introduction of Gigantamax Snorlax, but outside of that, the most significant update to the creature was the addition of its baby evolution Munchlax back in Gen 4.

After the Munchlax evolves into Snorlax, handing it the Snorlium Z Crystal will allow it to use Pulverizing Pancake Special Z-move.

Turns out the only thing harder than waking Snorlax up is defeating a Shadow Snorlax in battle. Currently, Shadow Snorlax is one of the hardest Shadow Pokémon available in Pokémon Go.
