Apparently, Happy's Cupcakes were quite popular. A few of the others looked interested in them. The Griffon seemed to enjoy them the most. He gulped down the first cupcake, and immediately helped himself to a second one. "Help yourself. I got plenty, and I can always make more!" Happy said with a smile. "Just, don't eat all of em before the others get a chance to have some themselves, kay?" 

According to the Zebra, they were in the middle of having some sort of demonstration. They were all paying attention to a Unicorn in the center. She took a breath, and in a flash of green light, she had transformed into a perfect replica of the zebra. Happy's eyes widened in surprise. "No way! You're a changeling?!" He had heard about the changeling invasion in Canterlot, and read about them in the past. All the books made them seem like evil parasites that want to drain love from everywhere. As far as he could see, they were only trying to find food. The Queen was the only one that was actually malicious, her followers were probably just hungry. You can't blame an entire race for the actions of one evil queen.

He ran up to the changeling. "Wow, that was awesome! I haven't seen a changeling in pony* before! Ooh, turn into me! Turn into me!" He exclaimed excitedly while bouncing up and down.
