Somehow I never would have imagined that .  His name is Grunt . Come closer and I'll properly introduce you .  Does it bite or scratch ?  No , he's perfectly harmless . And he's not afraid of strangers either . Here , hold him .  Wow . He's heavy ! And his skin feels really cool .  Stick around and you'll get to know him better . He has a very unusual personality .
