|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.
