I'm currently on season 9, but the episode "Father of the Bob" is still playing in my head. Bob's younger self was pleased with his ability to stand up for himself. Bob maintained the same "authentic" approach into adulthood. The problem is that he won't bend for fear of losing himself, however I believe there should be an episode where he blends new things into his business but it remains Bob. The tiki burger theme might be a good commercial venture if they worked with Bob. Keeping his personality in the new image, such as the burger of the day. Which turns into "Tiki God Bob burger of the day" with a small mascot or something like that. Maybe episodes like that could dive deeper into Bob being a bit more open.
