In the ending credits of Guardians of the Galaxy Vol. 2, some names appear as Baby Groot or I am Groot(1) before being replaced by the person's name. What does this mean?
(1) I don't remember the exact text
They all said, "I Am Groot". Because "I am Groot" means anything Groot wants it to mean. Including that person's name. This is the same as many movies or shows that have jokes in their credits. Like the Simpson's Little Tree House of Horror episodes where all the names are given funny horror themes or middle names.
