Rool's announce trailer "The Rivals", Donkey Kong and Diddy Kong when witnessing King K. Rool knock away King Dedede (who had posed as the Kremling leader as a prank) had their eyes comically bulge out far enough to shatter part of the windows of the treehouse in horror, referencing Diddy and Dixie Kong's reactions when about to face a boss in that game (and to a lesser extent, Donkey Kong's reaction whenever Kaptain K. Rool regains consciousness and starts the next phase of the final boss battle).
