In the Despicable Me franchise, Bob is the Minion who wears two different colored eyes.
Bob is commonly depicted with heterochromia: one eye is brown and the other is green. He is also recognizable for his small size, bald head, and teddy bear, Tim, which he carries in the Minions films.
Bob is one of the three central Minions in the 2015 film Minions, alongside Kevin and Stuart. The trio travels away from the Minion colony to find a new villainous master, eventually meeting Scarlet Overkill.
The eye-color detail can be confused with other Minion design traits because the characters share similar goggles, overalls, and yellow coloring. Kevin is taller and wears two eyes, while Stuart is a one-eyed Minion. Bob’s mismatched eyes are his distinctive identifying feature.
