Kevin, Stuart, and Bob were picked because their suppose to represent the different ages and behaviors of Minions. Kevin's the oldest, most mature, Stuart's the middle, and has a lazy slacker attitude, and Bob's the youngest, and has a childish approach to everything (like in the mall where he's distracted by the mirrors and thinks their other minions in the reflection, which is why he got upset when he they were "moving away", or when he's king and is uncomfortable by all the people, so he has them dress as other minions). In addition, their apparences are all the common shapes of a Minion: Kevin has a tall head and little bit of hair on his head, Stuart has one eye and has a normal-shaped head, and Bob is small, plump, and has two eyes  (in his case, different colored).
