Legendary dragons are some of the rarest and most powerful dragons in Dragon City. They are intentionally designed to be difficult to obtain through breeding in order to maintain their exclusivity and value. To obtain legendary dragons, you may need to participate in special events, complete specific tasks, or purchase them through in-game offers. Keep playing and exploring different avenues within the game to increase your chances of obtaining legendary dragons. **

Breeding legendary dragons in Dragon City is not working because legendary dragons are extremely rare and have a very low chance of being produced through breeding. It requires a lot of patience and luck to successfully breed a legendary dragon. To increase your chances, make sure you are using the correct combination of dragons with the highest rarity levels and keep trying different combinations until you are successful. Good luck! **

To breed the legendary dragon in Dragon City, you will need to breed two specific dragons that have the elements required to create the legendary dragon. The combination of dragons needed to breed a legendary dragon varies and can be found in the game's breeding hints or through online resources. Once you have the correct combination, you can place the dragons in the breeding mountain and wait for the breeding process to complete. Keep in mind that breeding legendary dragons can be challenging and may require multiple attempts before successfully obtaining the legendary dragon. **

A fire-breathing dragon would likely have to be very careful when blowing out his birthday candles, as his natural ability to breathe fire could easily cause the candles to ignite. He would probably have to use a gentle, controlled breath to extinguish the flames without accidentally setting anything else on fire. Alternatively, he could ask for help from a friend or use a magical spell to safely extinguish the candles without causing any unintended fiery mishaps. **

A dragon doesn't burn its own mouth when breathing fire because it has evolved to have fire-resistant tissues and scales in its mouth and throat. These specialized adaptations protect the dragon from the intense heat it produces when breathing fire. Additionally, the dragon's ability to control the direction and intensity of its fire breath allows it to avoid burning itself. This combination of physical and physiological adaptations enables the dragon to safely breathe fire without harming itself. **

The word "dragon" is singular, referring to one mythical creature. The plural form of "dragon" is "dragons," which is used when referring to multiple mythical creatures. So, it is called "dragon" when referring to one, and "dragons" when referring to more than one. **

Rare dragons in Dragon City are dragons that are harder to obtain than common dragons. They are usually more powerful and have unique abilities compared to common dragons. Rare dragons can be obtained through special events, breeding combinations, or by purchasing them with in-game currency. These dragons are sought after by players for their strength and rarity. **

No, fire-breathing dragons would not be biologically possible. The ability to breathe fire would require a biological mechanism to produce and expel a flammable substance, as well as a way to ignite it. There are no known biological systems that could accomplish this, and the energy required to produce and expel fire would be impractical for a living organism. Additionally, the heat and pressure from breathing fire would likely be harmful to the dragon's own body. Therefore, fire-breathing dragons are purely a product of mythology and fiction. **
