So, any proof that the Hammerhead Bros. and Mine Cart Owner are Hoohooligans and not just Beanish? Niiue (talk) 04:10, 13 August 2017 (EDT)

Mine Cart Owner has the right body structure, it looks like. As for the Hammerhead Bros., I'd say to remove it unless any proof comes up. However, I think you should change it back to having Beanish as the parent species, they're about as similar as the various ugly-designed Toads the game had.

The problem is, Beanish have varied enough body types that the Mine Cart Owner could easily just be a normal Beanish. Niiue (talk) 04:21, 13 August 2017 (EDT)
