Looking back at the unused sprites with the honey, I think it might be an indication that Wasplings, enemies from Battletoads in Battlemaniacs were meant to make a return in Stage 4 (The game itself contained unused beehive mentioned in the manual), but they were replaced by Groggs later in development perhaps?
(Speaking of Stage 4, there were rumors that Karnath was the original boss there. Which might make sense, considering how we never see the bottom of the level at the end.)
