But turns out, there's another reward for completing the Pokedex! Here's everything we know about it.

After completing your Pokedex, make sure to investigate (and we mean really dig deep!) in Sparkling Skylands. Nearby the cave where you meet Gyarados for the first time, you'll stumble across a room with a broken ladder. Follow the black and yellow strip WARNING panel on the floor, and you'll locate a secret area.

To enter the area, break through the panel and drop down into a small cavern. What awaits you inside is an Area Gate that lets players scan their Pokedex. However, you'll only be able to do this once you've completed the Pokedex, which means finding all 300 Pokemon. This doesn't include event-only exclusives.

In the Area Gate, you will also find a recipe for a card reader, a shutter for the door that opened up, and a printer. Approach the printer to receive a certificate congratulating you on completing your Pokedex. It's absolutely adorable and can even be hung up - but for the sake of mystery, you better find it yourself to see what it looks like!
