so Thomas is getting symptoms of the wolfpony transformation but he does not know it yet.

these symptoms benefit him though here are the explanations

Thomas can now smell for miles that he can smell a new cake from a house far away

he is stronger now and can left more heavy objects

Thomas can hear things from far away too even birds singing

Thomas has more energy and is more playful like a puppy and can hang out with dogs though other ponies find this weird

wolfponies have these abilities but young wolfponies are more playful than adults but they can play too

not much else to say here, for now, the next part will show the "bad" part of the side effects i say "bad" because is natural for a wolf pony
