Hop on the Purple Line and head up to Evanston if you're looking for a Sandshrew. This classic Pokémon has been spotted on the Lakefill on the Northwestern campus.

Squirtle is one of the oldest and most recognizable Pokémon. There have been sightings of this water Pokémon around the trails in Winnemac Park.

Water Pokémon are most commonly found near... well, water. Head over to Montrose Beach to find water Pokémon like Staryu.

Like Squirtle and Charmander, Bulbasaur is one of the original starter Pokémon. This classic pocket monster has been spotted in Independence Park in the Irving Park area.

There are lots of Tangelas spawning at Chopin Park throughout the day. They're not so much rare as they're just really only found at this particular location.

Meowth isn't as rare as others, but it's certainly more interesting that Pidgeys and Rattatas. This Pokémon has been spotted in Lincoln Park's Wrightwood Park.

Perhaps the most visible mascot of the game, Pikachu is an adorable creature that uses lightening to defeat its enemies. Head to Humboldt Park to find this Pokémon. There are plenty of Pikachus in the area surrounding the Jens Jensen-designed Formal Garden

Imagine having a Scyther watching over your local gym. It's certainly cooler than Pidgeots and Raticates. You'll want to have some Master Balls in your backpack when you head over to Washington Square Park to find one.

Clefairy is not a tough guy Pokémon, but that doesn't mean it won't put up a fight. This fluffy Pokémon has been spotted in and around Connors Park.

Voltorb is not your typical cutesy Pokémon—it's basically like a Pokéball that has been possessed by a demon. If you want to catch one of these, walking around Navy Pier is a pretty solid bet.

Perhaps one of the more bizarre Pokémon, Exeggcute has been spotted around Millennium Park—specifically the area around Wrigley Square.

In the original Pokémon games, Diglett and its evolved form Dugtrio was a formidable opponent. If you can catch one and strengthen it up, you'll be the envy of your local gym. Word on the street is that these guys can be found around Cloud Gate (The Bean) in Millennium Park.

Charmander and its evolved forms was the mascot of the original Pokémon Red game that was released back in 1996 for the Game Boy. If your collection isn't complete without a Charmander, head over to Sheridan Park with a few Pokéballs and an incense.

If you're seeking a Vulpix, Pilsen is the place to be. They've been spotted around Harrison Park.

You'll be the envy of your local gym if you can catch a Dratini. They've been spotted in and around Cicero Community Park in Cicero.
