Bubbles sure is cute! I do not have enough experience identifying frogs, so until someone else jumps in and gives a positive I.D. I am not going to confirm or deny Bubbles is an American Bullfrog. I was going by the first pictures you posted, because those pictures look almost identical to my Poe who I know for sure is a bullfrog. Paul, can you say for sure what Bubbles is based on the new pics?
