Whoops, that's NOT Pikachu!

A group of sisters playing Pokemon Go in Denver came across a baby gator or caiman in the Goldsmith Gulch this week. Denver7 reports the 3 girls spotted a Pikachu when they came across the "Gator of Goldsmith Gulch" along Tamarac Drive.

One of the girls guessed the reptile was about 2 feet long.

The girls' step-father contacted Animal Control following the sighting, but hasn't heard back as to what kind of reptile it actually was.

Surprisingly, this isn't the first time this week that a large reptile has been spotted in Denver. Last Sunday, police caught a caiman in the front yard of an Aurora residence. Now, obviously gators and crocodiles are not native to Colorado. Dwarf caimans, however, are often kept as pets and can grow up to 5 feet long. Full-grown alligators can be between 9 and 15 feet in length, says Denver7.
