New Arrivals: Tyrunt, and Tyrantrum

There have been reports of Pokémon appearing that we haven’t seen around here before—maybe this is thanks to the sleep research you’ve all been conducting! It may be possible to encounter them during sleep research sometime soon.

We hope you’re looking forward to this!
