Basically Dr. Jekyll and Mr. Hyde but with a more blueberry twist. Oliver Berrykl is essentially Dr. Jekyll, while Maxwell Blue is Mr. Hyde. Maxwell Blue (Aka Mr. Blue) is a more “mad scientist” take on the character, wanting to swell up one of Oliver’s only friends with blueberry juice, using a potion that Oliver was working on. Oliver is in control of both halves. Oliver hides his secret obsession with blueberry inflation, Maxwell pretty much expresses it (even pulling out the needed potion).
