Mikey R.

Mikey R. is a character in Gravity Falls.

Headhunters
Mikey R. was present during the re-opening of the Gravity Falls Wax Museum. He, like everyone else, was disapointed when it turned out that there was no free pizza at the re-opening.

He was also considered a suspect until Dipper and Mabel found out that both of his arms are broken.

His appearance could be a oblique reference to Harold Smith from the television show Twin Peaks.
