The Ghastly Zapplejack's behavior falls somewhere in between that of each parent. The two heads are very caring and protective of each other. Additionally, they are fairly passive and do not like conflict, even among other species. However, when goaded into acting, they can be fierce protective fighters.
Ghastly Zapplejacks, particularly Orchard Zapplejacks, love fruit and can be easily befriended by presenting them with some.
The Ghastly Zapplejack was first introduced in this game, along with many other dragon hybrids. The only way a player can obtain a Ghastly Zapplejack is by breeding a Hideous Zippleback and a Timberjack in the Breedery.
