以a dragon that provides the Blue type跟a dragon that provides the Red type繁殖。 If a parent has the appropriate minor colors, missing requirements may also be added to the pool, even if neither parent has the originally required color types.
As a random single color result of breeding two pureDiamond color dragons together (Diamond only). This pairing may result in any currently available pure dragon of the Red, Green, Yellow, Blue, Purple, White, Pink, Black, Mythic, Cosmic, Fairytale, Stone, Dino, or Diamond color. Dragons that are not valid offspring, such as crafted or goal dragons, cannot emerge from this pairing.
When the Tropic color is alone in the color pool, it will add pure dragons of its component colors () to the list of possible outcomes, but it will not split into its component colors. When Tropic is included in the color pool along with one or more other colors, the Tropic color can split into . However, if it is split, then Tropic is no longer in the pool for the duration. Thus, the presence of Tropic in a pool will either add the Tropic color if it does not split or the colors if it does split.
When considering hybrids of the Tropic color whose other colors are all split color components of Tropic (), the Tropic color may contribute both Tropic and its split colors () if both parents have the Tropic color. Currently, no hybrids of this kind are available. Keep in mind that the Tropic color will not split if it is alone in the pool, so you must use at least one Tropic hybrid as a parent if you want to take advantage of this method.
Although the Tropic color can split into for breeding purposes, it still only counts as one color. This is important when considering the number of colors for color-amount-dependent dragons such as the Diamond Dragon. Breeding a Tropic Dragon with a Coral Dragon only counts as three types: Tropic, Blue, and Purple.
The 熱帶龍's design is based upon the Air Dragon's, although there are differences between the two.
