Henry walked out of the castle, onto the grounds with nothing but his wand in his hand. Henry came out here to practice turning into his animgues form, and he knew this would be a good spot to do so.

He took out his wand and waved it, hoping to turn into a Bernease Moutntain Dog. But it didn't work. He tried it again and he worked. He then barked, because he was happy that it worked. He then walked around a little.
