The Pet Teacup Dragon was an April Fools joke posted by the official Animal Jam Instagram (@animaljam).

"Not to be confused with the Hungarian Horntail, the Pet Teacup Dragon is all about cuddles and over sized poofy blankets. We are exited to welcome these wonderful new pets to Jamaa. Please make sure to NOT invite your pet teacup dragon inside a small den, we can’t be responsible for the overhead structure damage that they may ensue. These pets need room to breathe and romp, preferably in an ample open space or trampoline. Have fun, Jammer! #AnimalJam #PlayWild #AJTeacupDragon."
