Fluttershy kept in touch with Dr Caballeron. So when she found out his youngest son's interest is to learn more about the unique creatures, monsters and animals of the world and seeing them, she thought he would love to meet the two known draconequuses (this was before Mayhem and Anarchy born). Needless to say, young Gutsy was excited to do so.
Refresher, Gutsy is the youngest son of Dr Caballeron and Daring Do. He's a young teen here.
