How is a 50 year old creature that infantile in behavior?
I understand baby Yoda is cute. I understand that with a lifespan of 900+ years, a 50 year old of this species can still be infantile in physical development. But that creature still has 50 years of life experience.
Did it just sit in a stroller all day and nap for 50 years? WTF has it been doing all this time? Why hasn't it developed language and communication skills in 50 fricking years?
