No Night is Eternal

After Kirby, Bandana Dee, and Elfilin defeat Fecto Elfilis and Return to Dream Landâ„¢, Elfilin flies up to the massive portal in the sky and uses the last of his power to close it, and seemingly dies. As Kirby mourns, a light shines behind him, and it is revealed that Elfilin was able to survive the portal collapsing, and that the surviving Beast Pack has befriended King Dedede, Meta Knight, and the Waddle Dees of Waddle Dee Town. Yay! :D
