The definition is at the beginning of the clue.
How the clue works
Start with the wordplay: "some characters in" tells you the answer is hiding inside "field day", and "retro" says it's running backwards. Read "field day" in reverse (yadd-leif) and ADDLE pops out in the middle. That gives you Befuddle for the definition.
