Not to detract from the accomplishment, but none of these are Kermit. The "Kermit" part of the query seems mostly to have accomplished querying for "humanoid frog"
I don't have access to DALL-E 2, but I wonder if a prompt like "A cameo from Kermit the Frog in ..." would give more literal Kermits.
"To me those are clearly Kermit the Frogs."
"To me those are clearly not Kermit the Frogs."
Then there's nothing really to argue about. Instead we can discuss what we see and how that affects our subjective perceptions.
For example, Kermit the Frog doesn't have eyelids, but most of these images show a frog with eyelids.
