Minions

Minions are the most iconic animated characters of their generation, recognized and beloved around the world, by fans of all ages, in every language and culture. Minions and the series of films are the highest grossing animated franchise of all time… and they speak Minionese!

They're earnestly driven by the desire to serve an evil boss, though they often screw up because they're selfish, easily distracted, and generally inept but yet very funny. They communicate using a gibberish language that's understandable to them and a few people who have longstanding relationships with them.
