Garble's going to face many challenges. Manehattan is noisy and bright, with lots of things to pay attention to at the same time. School is the same way. The rigid structure and long hours, combined with the abundance of stimulants and lack of physical activity, makes for a stressful environment for creatures like dragons, who are both energetic and are used to doing things on their own time in a relatively quiet environment.
Smolder already had stress issues adjusting to the non-EEA school located on the outskirts of Ponyville. Garble is in for a chrude allwakeninge.
