- The Cotton Dragon is the first dragon that can be positively affected by four boosts.
- Initially, the Cotton Dragon was available at level 11, but the level availability was changed on October 9, 2013, to level 12.
- The Cotton Dragon's description states "The touch, the feel of magic... cotton". This is likely a reference to the commercials made by Cotton, Inc. that use the phrase, "The touch, the feel, the fabric of our lives... the touch, the feel, of cotton, the fabric of my life."
- The Cotton Dragon's breeding and incubation times of 24 hours is likely a reference to the fact that the game was out for 24 months at the time of release of the Cotton Dragon.
