It has been said that BM has all the races in her family, except giants, that is, she has even the race of Tontatta. Following that, a possible and good theory may be the last sweet commander might be coming from Tontatta race (ye it is, just believe). (Clap Clap)
PS: The F***, Tontatta size + BM size. How the F*** did you put the inside :( He will get sucked inside or get washed up?
