Twin Woods makes its first appearance in the Revenge of Meta Knight sub-game, being fought immediately after Kirby defeats Whispy. Most of Twin Woods' attacks are the exact same as the regular Whispy's attacks. They can also switch pieces of their trunk and drop bugs (that Kirby can't inhale) and Gordos.
- Even if Kirby enters the boss door in any other season, the battle will still take place in Summer in Kirby Super Star or Autumn in Kirby Super Star Ultra.
- In Kirby Star Allies exists a boss with a similar concept, namely Twin Kracko, the second phase of the original Kracko. Although not directly a copy of the original Kracko, like Twin Woods with Whispy Woods, the concept behind it is mainly the same, being a team of two twins.
