|Affiliated Decoration: Butterfly Pavilion|
- In addition to its affiliated decoration, the Butterfly Dragon was released along with the Plasma Dragon, and the hidden Current Dragon.
- The Butterfly Dragon is the first dragon with wings that have two independently moving parts.
- Initially, the Butterfly Dragon was available at level 14, but the level availability was changed on October 9, 2013, to level 16.
- The Butterfly Dragon's description mentions, "wingaling dragon". This is likely a reference to Trogdor The Burninator, the "wing-a-ling dragon" on the online game, Homestar Runner created by The Brother Chaps.
- The Butterfly Dragon's description mentions, "flightless as babies". This is likely a reference to the stage of a butterfly's life when it is a caterpillar.
- The Butterfly Dragon's description mentions, "lush Sykie". This is likely a play on the greek word "psyche", meaning butterfly.
- The pattern on Butterfly Dragon's wings resembles eyes, which is similar to how some butterflies and moths have eye-like patterns on their wings to scare away predators. Additionally, the lower tips of the wings resemble nostrils and the tail possesses spines that resemble teeth. All three elements combined mimic a dragon's chomping mouth when the dragon adjusts its wings vertically.
