Misha (or Mishka) is the much beloved mascot created for the 1980 Moscow Olympic Games. Isn’t he cute? (he IS though) (don’t you just want to stuff him in your pocket and take him home?)
And just in case this isn’t common knowledge: Misha is a short form for the Russian male name Mikhail (Michael), and Mishka is a diminutive of Misha. This name, in any of its forms, is a common colloquialism in Russian for a bear, because it is similar to the standard name for bear медведь (meddled).
