How to Catch These Pokemon in the Sinnoh Region: Diamond & Pearl Edition

In Pokemon Diamond & Pearl, there are plenty of fantastic monsters waiting for a trainer! From all-time favorites like Munchlax to more intriguing Cresselia, the Sinnoh region might surprise you and challenge you at the same time.

But, some ‘mon are easier to catch than others, and if you’re having a hard time doing that, there are a few tips and tricks. We have put together a list of the most challenging Pokemon to catch in the Sinnoh region.

Here is what you need to know. You can catch the following Pokemon by doing this:


Shaymin is a lovely Pokemon that you can find in Pokemon Platinum after getting an Oak’s Letter from a unique event. Next, head to Route 224 (connected to Victory Road) and look for Professor Oak.

The Oak’s letter will finally grant you access to Seabreak Path, where you’ll find Shaymin!


Cresselia and Mesprit are roaming Pokemon, so catching them is quite the challenge! Both ‘mon are Psychic-type Legendaries and you can encounter them via the National Dex.

To catch them, you have to try and ensure they don’t fly.


This Legendary titan has almost the lowest capture rate, 3 %, so you can get why it’s so hard to catch it. However, that doesn’t mean is an impossible task.

First, you need to get the National Pokedex and go to the Snowpoint Temple. Then, you’ll have to solve various puzzles, so you’ll get access to the final floor.

Now, to awaken Regigigas is another story. You need Regice, Regirock, and Registeel.


Rotom is a dual-type Electric/Ghost Pokemon and a Legendary encounter.

There is only one way to catch Rotom. You have to interact with the TV and wait for a spooky surprise. The TV is inside the Old Chateau (be careful, it’s easy to miss).


Catching Munchlax has been always a challenge because it spawns like no other species in the Sinnoh region.

Try to spread some Honey on the side of a Honey Tree and wait for six hours for Munchlax to appear. This Pokemon loves munching on the berries atop Honey Trees.
