Oof, that's a big error on my part! The book was published in 2000, I don't know how I managed to mix that up twice in my script! 😱Thanks for the correction! I've pinned your comment and added a note to the description too to make the correction as visible as possible!
When I saw that Kerog looked just like bowser, It made me think of another odd Nintendo villain which is "Bowsers twin". he's just bowser but recolored and only ever apeared in Mario 2 (Lost Levels)
I wonder what the meaning behing K_Kerog is. King Kerog? Almost sounds like a portmanteau of the japanese word for ribbit 'kero' and the english word 'frog.' Would be a great pokemon name.
